I have traded more NINTENDO products in my LONG gamelife, then I care to remember some of which I have rebought ... Silly me. BUT a good game is Just a good game and sometimes one does not know how much "crap " is out there, thinking its better then the decent stuff you have played already.... some games however just do not make it to the "I'm gonna want to play this again" title file either .

Thrillville Off The Rails, because it's crap.

I made the HORRIBLE mistake of trading in all my ds games and my DSi because I got bored.
I wish I had never done that.
I don't even remember all the games I had.

It's a 3DS game, but yesterday I got rid of Rayman 3D because I hate that game.

Pokemon pearl and pokemon white got stolen by a friend of mine
I gave Disney friends, spectrobes and a wario game to my brother because i didnt like em.

I sold Spectrobes that my friend gave me for free, and I lost Mario Kart DS along with my DS Lite.... then 6 days later I got a 3DS and Mario Kart 7. So it's all good.

Call of Duty 4: It was amazing fun, but no one else had it for DS, so I was alone. My DS Lite's L and R buttons also died. I may buy it again if it's cheap enough.

Call of Duty Black Ops: It was worse than Call of Duty 4 in every regard except graphics and modes. The overall game was choppy and slow. It didn't feel as complete as the more barren Call of Duty 4.

Children of Mana: Incredibly short, not fun enough to keep me playing longer than once.

Dragon Quest IX (first time): Gave it to my bro because I got bored. I bought it again a couple months ago for $10.

Kingdom Hearts 358/2 Days: Don't know why I sold it. Second best DS game I owned. Fun, great story, incredible fighting, challenge, lots of replay value (for average completionist, experts...not so much).

Legend of Kay: It was bad. Gave it to a friend and he sold it.

Naruto Ninja Council 3: Fun, but gets REALLY BORING after the 1,000,000 playthrough.

Naruto Ninja Council 4: Good. Went back to sidescrolling roots of series. Not the same charm as Ninja Council 2.

Naruto Ninja Destiny: Amazing fighter. Sold it because I had the sequel

Naruto Ninja Destiny 2: Amazing fighter. sold it because it was good, but once the campaign was beaten, it got old.

Naruto Path of Ninja: Great Naruto RPG. Follows story from first episode to Gaara fight. Not much to do after unlocking everything (which doesn't take long.)

Orcs & Elves: Great game, amazing graphics, short story. Sold it because I needed money for another game. If I ever find it again, I'll pick it up in an instant. 5 hours well spent

Pokemon Diamond (first time): Lost it.

Pokemon Diamond (second time): Traded it in because I'm stupid. Bought Pokemon Pearl off my bro for $20.

Phantom Hourglass: A great, intuitive Zelda adventure. First one I beat. Little replay after you beat the story...since all you can do is sail, find secrets, and sail. Might get Spirit Tracks in the future, though.

I could not beat Princess Shroob's twin sister for my life. I tried everything...except for using lots and lots of Mix Flowers.

-Robots (it was good but i needet a birthday present for somebody and don´t had money)
-Lunar Knights (I tradet it for Yu-GI-Oh spirit caller but i loved Lunar Knights so i may buy a new copy oneday)
-FIFA 06 (I don´t really like Football Games on handhelds)
-Pokemon Mystery Dungeon 1 (I don´t really understand the game when i was younger later I bought the 2nd Mystery Dungeon and loved it)
-Dragonball (gave it away because it wasn´t my kind of game)

I remember I got Mario & Luigi Bowser's Inside Story and then got rid of it because I wanted to get Kirby's epic yarn at the time instead but now I got it again and I love it, shame on me!!
Also: Sims 2 Pets (It didn't feel like the Sims and I couldn't enjoy it at all)
Rayman DS (Got Frustrating and DS version sucked)
Animal Crossing Wild World (it broke but I can't wait for New Leaf )

the only one I can remember is Nanostray because every time I started a level, I would instantly die. XD don't judge me though, I was 14 back then and I love shmups, especially 16-bit ones! another one from my head is Metroid Prime Pinball, though I shouldn't have traded it in

Pokemon Black and White: I bought them cause the last Pokemon game I played was Red and Blue so I thought I would give a newer one a chance, plus I think I got caught up in the hype. For me they were just like every other Pokemon game and I got bored with them and stopped playing them after getting the second badge. I wasn't going to play them again so I figured I might as well trade them in.

Metroid Prime: Hunters (While it was a very nice looking portable game at the time of its release, the gameplay is just awful. It has none of the exploration or magic of most of the other Metroid games.)

Super Princess Peach (I wanted to love this. The art is gorgeous, the role reversal is intriguing, and the inclusion of RPG elements is daring. Unfortunately, the game simply doesn't respect its audience enough to let them figure things out for the most part. I love that Peach's emotions can be used as a form of magic, but there was never any guesswork, The stupid umbrella holds your hand through the entire game. It COULD have been great had it left some guesswork to the player.)

Nanostray (Miserable little shooter. No fun at all.)

Nintendogs (Most frustrating, broken game I've ever played. The stupid dog was never able to remember my name!)

There is actually more variation in B&W than in most of the Pokemon games. For one thing, as you get deeper into the game, you would have noticed a stronger emphasis on overall plotline than most Pokemon games. Also, the level of multiplayer interactivity is pretty deep.

Had mario party ds but i traded a friend for his Sonic & All stars Racing. Its pretty good game and one of my favorites on the DS.

pokemon is still an keeper i have pokemon black 2

Nostalgia, it just didn't have enough content for me. Only about 30 hours of gameplay, story was meh, and nothing too special after beating the game. I think it's the only DS game I've gotten rid of.

what

We must not have played the same game. I found it to be a quality, engrossing effort in the genre with good music and fun boss fights. A good variety of weapons / special attacks as well.

I'm confounded as well.
