I know your just being silly but MGS2 MGS3 I have played thoose two and disliked them myself. Never played The killzones and Modern warfares but I am not a huge Fps fan so safe to say I would not care much for thoose too.

Oblivion (PS3): With this game I realized that I prefer Japanese RPGs over Western RPGs. Well, I gave it a try and I really wanted to like it, but it was a bit too "open" for my taste.

World of Goo (WiiWare): For 500 Yen I wouldn't have minded much, but I paid 1500Yen for it and then noticed that I don't enjoy it as much as I thought I would. And I can't even sell it like other disc or cartridge based games, because it was a download.

Final Fantasy XII
Splinter Cell: Double Agent
The Saboteur

nah I am just bitter because I should have just kept them instead...

awe that sucks. Guess you learned the a good life lesson. Never trade in or sale games you like

DMC4. Paid $100 dollars for a 3 and a half hour game that you have to play through twice.....horrid game.

1. Assassin's Creed - was hyped as hell for the game, expected much better
2. Buzz quiz world - glitchy online
3. Battle for Middle Earth 1 - Not building structures where I wanted blew it for me :(

lol i don't even trade in games i don't like. i keep em on the side with my dust and lice collection so that they suffer and are laughed at by the other games. it may not seem so in his games, but kratos does love to laugh, and it's a mighty laugh

can't really do it in order but i know the worst purchase i made was shadow madness. HATE that game. Closely followed by Double Dungeons (WTF??!!)

then in no particular order
forgotten worlds
clayfighter 63 1/3 (no replay value)

uh that's not nearly as bad as mortal kombat mythologies.  Trilogy was actually a good game if you liked mortal kombat, just that mortal kombat was starting to get really dull at that time.
