Postal III because I loved the first two games, but they decided to outsource the game to a Russian studio that seemed to think gamers LOVE escort and protection missions so they made 90% of the game with them. Gone was the open world of part 2 and everything else good about part 2. It was a really bad 3rd person shooter with clunky controls, terrible hit detection, the worst AI, and very little in the way of fun. It was so bad that the series creators disowned the game and removed it from their web store after vowing to never outsource their games ever again. I paid $40 for that s***.
Duke Nukem Forever and Aliens Colonial Marines so much hype and both games just sucked. With Duke, I get where Gearbox was because they spent a lot of money to buy the IP only to end up with a really bad game that they had to sell as is. Aliens was the case of them being too busy with Borderlands 2 so they outsource it to several studios which decided to throw everything out and piss on it so they could make their own Aliens game to the dismay of everyone.
Werewolf The Last Warrior the graphics and music were awesome for the NES but it just wasn't a very good game. The controls get really confusing like to this day I still can't figure out how to climb the pipes on the ceiling. The game is mostly throwing an endless stream of enemies from all directions. But look at the awesome box art, how could any kid not beg their parents to buy this game? http://image.gamespotcdn.net/gamespot/images/box/7/6/2/587762_47017_front.jpg
