yuck remembered another bad one. ever played them broswer based ones where you have to wait like 20 minutes for an action? yeah any game like that is on my hate list >.<
I'm pretty sure that there's a thread similar to this :/.
The worst games imo would be a lot of those games that were from a movie. For example: Transformers Movie The Video Game (or something like that, not sure..). When you first start the game everything is fun, but not too long after starting the game do you find it repetetive and boring. All the missions are the same, killing bosses is hard only because the boss runs away and makes you kill it's lackeys, and the way you kill enemies just suck.
There are other games I hate, but can't think of right now...
ET is really bad but even worse is an old game called armarines or somthing like that I cant remember. It was for the SNES (Super Nintendo) and cost like $100 and the game sucked so much thank god I only rented it for 5 bucks.
