The demo of Bit Trip Beat is so good, that I'm going to buy the game one day.
And that's all I tried.

They should do a demo of Star Soldier R. It would be like downloading a demo of a demo

Pokemon Rumble: After playing the demo a couple times I was convinced to buy it

MLAADL: It was ok. but there was hardly any game play... one could just sit back and watch the game play itself. I found it a snoozer

Icarian/NyxQuest: so far is a meh

I like this comment because what you described is a big reason why I did not enjoy Lostwinds. I didn't come here to bash LW though, but it did keep me from purchasing Nyx because I was so disappointed with LW. After playing the demo for Nyx though I loved it so much I immediately downloaded it after I played through the demo. To be honest if there had been no demo I would never have purchased this game. So the demo made flat out purchase the game.

Also the other demo that appealed to me was FFCC: My life as a Darklord. After the demo I would say I am more likely than I was to purchase before. but im investigating the DLC content to see how much this game will "actually" cost me. I'm not talking about costumes, which I won't buy anyway, but the extra enemies and monsters.

I hope that Europe gets the Pokemon demo this Friday, I'm still in doubt.

I was convinced to get Pokemon Rumble at some point, without the demo it would've been skipped.

I had passing interest in Nyxquest, and now I know I like it. So it helped a bit but I may not get it.

Bit Trip Beat didn't look all that appealing to me, and the demo confirmed my initial thoughts.

I had forgotten about Darklord without the demo, but I won't get it as it played much too slow for me to enjoy.

After playing Bit.Trip.Beat for the first time (the demo) I WANT IT!

I downloaded the Demo's for the US and I told everyone I know with a Wii and enough grey matter to get it online to download them so that we can keep the demo service. But anyways, Mr. Chicken, the follow:

FFCC: My life as a Dark Lord - I was thinking about it, but after the demo, no, I don't want it
BIT.TRIP.BEAT: Didn't think about it, but after demo, still no, I don't want it
Pokemon Rumble: I heard of this game, I played the demo and I have to say it is a possibility
Haven't play the Icarus knockoff yet

That's just stupid. NyxQuest/Icarian is in no way a knock off of Kid Icarus. Ok, (very) rough setting wise yes... Sure, that one I give you maybe. But gameplay wise... Couldn't be more wrong. For example, take every single FPS game ever and they are more ripoffs of each other than NyxQuest of Kid Icarus. Heck if NyxQuest is an FPS, the Kid Icarus is a FP racing game... Like Test Drive (the old ones) or Hard Drivin'. Really, other than some really basic things (they're kinda based on the same source material, although each game has deviated from that source material in completely different directions), there are no similarities between the games.

Yeah Old School the Nyx related to Kid Icarus knockoff is very very ignorant. The game isn't like it at all. Try playing the game before you make comments like that.

The data, as of post 50. Collected from this thread only. (Other opinions on the demos have been posted elsewhere, but it'd be impossible for me to collect them all reliably.) I had to do some interpreting of what people were saying, but any interpretation that I couldn't make confidently, I just disregarded. I'd rather lose the data than misinterpret it completely and skew the results. (This only happened once or twice.)

It seems that the Pokemon Rumble demo was the most successful, convincing the most people to buy it, making only one person less likely to buy it, and turning nobody off completely.

I'm assuming the World of Goo demo had a comparatively small amount of feedback because so many people owned the full game already, so this probably means very little.

Bit.Trip: Beat seems to be very divisive. It's leaning slightly toward being a more successful demo (from a sales point) than an unsuccessful one, but only slightly. A few more responses could easily balance it out, or even tip the scales the other way. Very interesting. I had assumed Bit.Trip to be a "try it and love it" kind of game...and I think I might have been wrong about that. One thing I've noticed about the comments is that this game tends (overall) to reinforce whatever preconceptions people had about the game. "I thought it looked pretty cool...and it was!" "It looked confusing...and it gave me a headache."

NyxQuest seems to be a mild success. That's understandable for a slower, more contemplative sort of game however; it simply won't appeal to everybody. It does seem like a good percentage of people are giving it a shot, at least, and that's all that anyone can really ask.

Darklord seems to be the nearest thing to a failure as a demo...it convinced only one person to buy it, and four to skip it. While it did nudge a few folks nearer a purchase, the amount of people it drove completely away from one cancels it out. (Statistically speaking.)

By all means keep replying. I still need to play the demos myself, and I'll post my impressions here. I'm fascinated by this. Not so much by which games are best, or which games people most enjoy...but which demos most successfully lead their audience on to make a purchase.

Add me to the "convinced to skip" on Nyxquest. It bored me greatly, and I find the overly spartan visual style depressingly dull.

Actually, including Pokemon in the comparison here is a bit unfair... I mean, unlike all the other games, when the demo launched, no one owned the game. Most of those that demoed the game and was "convinced", gut feeling tells me that in a demo free world they would have bought it anyway...

Thanks for the data, Chicken! I ended up buying Excitebike and NyxQuest last night, so OverTheTopGames got at least one sale out the demo.

It would be unfair if I was comparing them to each other, but I'm not. (The interpretive flourish at the end is my own interested musing and not any hard conclusion.) I'm comparing the ratio of purchases to skips, and for that reason the only advantage Pokemon would have is in the number of people who tried the demo. And that's not being used to come to any sort of conclusion at all.

In the "demo-free world" you cite, where everyone purchased the game, there doubtless would have been some dis-satisfied customers. The demo allows many of those customers to realize ahead of time that they'd be dis-satisfied, which would thereby make this information MORE valuable.

Oddly, for whatever reason, none of those potential dis-satisfied customers posted in this thread.

I wish I had tried the MLaaDL demo before buying it. I enjoyed MLaaK very much (and still do), so downloaded Dark Lord on the back of that. Little did I know how different it would be, and how much it would bore me.

Am I really the only one?

actually chicken you can take my more likely to buy for MLAAD and change it to purchase. I think the thing that is scaring alot of people off about the game is the huge amount of DLC and I don't blame them. I bought it by convincing myself that I will not purchase any add on content.

ffcc:already own it
nyx:convinced to buy very cool looking game love the visuals and moving stuff
beat:less likely to buy doesn't look like my type of game:
wog: so-so but the high price and the fact that the difficulty is mildly high just in the demo puts me off
pokemon rumble:convinced to buy real time gameplay 4-player multiplayer and last and first gen pokemon all in a 15$ title need I say more

Just the only one who responded here. I've seen plenty of impressions in other threads where people say, "All you do is press 2!" Presumably they've played the demo if they realize even that much, but they didn't post here. I'm genuinely fascinated by this, though, so I'll update at some point after we get more replies. I doubt you'll be the only one for long.

For now I'll leave it so that my "as of post 50" comment stays accurate, but I'll make the change in the next update. Thanks!
