Prototype- still my biggest regret for purchasing this entire generation. Felt quite cheated getting that game.
Gears of War- was actually the first 360 game I bought, around when it came out and played on my bro's 360. Was my first slap in the face that all the good graphics in the world couldn't save this game being worth $60. Eventually bought it again (traded it in for a Wii game haha) for 1/6 of the price. Much better deal imo.
Street Fighter IV (360)- not that it was a bad game, but was the first and last time I was going to buy a fighter like that on the 360. Just couldn't play it with the 360 controller
Excite Truck- one of the 5-6 launch Wii titles I bought, and easily the most disappointing and I had bought Red Steel. Controls didn't work and never have worked for the title. Spent hours trying to play it, but never could.
Call of Duty Modern Warfare: Reflex- bought this the first day it came out, because I'm relatively fond of Wii FPS. However, this was the worst one I had played since the launch FPS games. Controls, I simply could not get to work in the title, and I'm a pro with Wii FPS controls. I spent an entire 2 hours straight playing with the control settings, trying to figure some combo that would make it work but never could. Was highly disappointed, because World at War controls were spectacular.
PS3- now this isn't to troll but simple explanation. I bought it 2 months before it dropped in price $100 and before I would have got 40 gb more hardware space for a cheaper price. Felt ripped haha.
