Probably. If I think a game's disappointing, I won't spend a lot of time with it. If I find it amazing, I'll spend tons of time with it. 3 of my Top 5 favorite games of all time are my Top 3 Most Played.

But why is that? I just don't get. Some absolutely fantastic games don't have that kind of replayability. Wouldn't it be better to measure the quality of time rather than the quantity? I really just don't understand it.

A tough tie between Super Mario Galaxy 2 & Legend of Zelda: Skyward Sword

@CanisWolfred
I get a lot of my replay value off of how fast I can complete a game, sometimes not even being able to judge such speeds by a game timer. I don't have to be dealing with multiplayer or a ton of quests in an RPG to rack up plenty of playing time, though they certainly can add to how much time I end up spending. I am judging my experiences by their quality. It's their quality that has me sinking so many hours into them. Why would I be playing a game potentially above 100 hours if I don't feel the experience is that of quality? Before playing Xenoblade Chronicles, I continually put Final Fantasy III (DS) on hold and have not completed it to this day. The RPG elements weren't what kept me engaged with Xenoblade Chronicles over triple the playtime I put towards FF3 (DS), it is the overall quality of that experience and how it all came together to have me engrossed when playing.

It's not that hard to understand, is it? Video games aren't free and everyone wants more for their money. If an eight hour game can cost the same as a two-hundred hour game, which is the better value? Even if that eight hour game were good, it still cost $40, $50, or $60 just to occupy you for one weekend. In that case you would have been better off spending a dollar at Redbox.

Donkey Kong Country Returns for me, I really got into the Shiny Gold Time Attacks, so it was a great 20 hours first time run through, with another 80 hours getting the medals and secrets, best of both worlds.

A close second for me (if you can't tell by my avatar) is Bit.Trip Complete, I could cycle through the six different games almost endlessly...

Of course this is only from the games I've played, so that could change in the future...

Brawl for me.

1. Super Mario Galaxy. The first game had more of a whimsical feel for some reason along with a better story. In actuality, 2 was definitely the better game, but I still had more fun with SMG1
2. Metroid Prime Trilogy. 3 awesome games on one disc.
3. Bully: Scholarship Edition. Had a load of fun with this one. It took a pretty decent sandbox game and improved it a lot, even with some minor problems.
4. Rhythm Heaven Fever. I'm a sucker for rhythm games.
5. No More Heroes 2. I only played this recently compared to the others (finished maybe a month or two ago) and I probably can't judge it too well, but I loved the first and this simply was a much better game.

Well, at a certain point, a game is going to feel like a grind unless they developed it for a LONG, LONG time. Regardless, I do think length is a pretty major factor, but not the sole factor. If I bought Portal for $40, I'd be pissed the hell off. But I'd much rather have a quality game that lasts 12 hours then a mediocre one lasting 50.

Extremely hard for me to decide between Prime Trilogy, Brawl, and Galaxy, but I have to go with Brawl. easily the most time spent on that game. It is the defition of a perfect multiplayer fighting game. If you haven't ever played a game in this series, you are really missing out. Check this series out!

To quote Kyle Gabler, a man I always quote when game length comes up:

1. Brawl
2. Galaxy
3. Donkey Kong Country Returns
my opinion

Super Mario Galaxy 2, bit disappointed with this gen's Zelda games in comparison to previous generations whereas I think Mario really raised the bar.

Purely for the sake of choosing something that hasn't been mentioned yet, I'll say Dragon Quest Swords. I'd love that game to get a sequel on Wii U, but it'll never happen JRPG/rail shooter is the greatest genre ever conceived

DJ Hero 2 + The Beatles Rock Band= the best Wii Music games.

Super Mario Galaxy!

The Legend of Zelda: Skyward Sword!

I have yet to play Galaxy 2, Skyward Sword, DKCR, A Boy & his Blob, Kirby's RTDL(aside from a few or so levels), Pikmin 2, Rayman Origins and a few other amazing titles, BUT as of now I consider these the Best of the Besty'

1. Wario Land Shake it!
2. Metroid Prime 3: Corruption
3. Klonoa
4. Zack & Wiki
5. Super Paper Mario
6. Super Mario Galaxy
7. Elebits

You need to get on DKCR pronto Wavey, quite possibly one of if not the best platformer I've played. I love a good challenge so that may be part of it as well. Rayman Origins, Kirby's Epic Yarn/Return to Dreamland, and yes, New Super Mario Bros Wii were all great 2D platformers too.

Only thing I have to add to this is...

Super Smash Bros. Brawl!

I've already got those unplayed Wii games i mentioned in my collection. I'm gradually starting to make my way through them all, but as of now I'm going to donatello & dip into the Stereo Scopic 3D-ified' Goomba Rilled Super Mario 3D Land tonight. tee hee.
