Who says a game sucks? What's the criteria? I hate when some moron reviews a game and gets it wrong. How can a review be wrong? Well for starters many people bashed Duke Forever. Oh, it's not modern enough, it's too demeaning, yadda yadda. Um it's Duke. Duh. I bought the game for about $20 and enjoyed it all. Screw the reviews, I knew what to expect and didn't spend $60 to find out. I hated RE4 for taking a good series and turning it into a shooter, however I liked RE5 better since the Move made it more a lightgun shooter. Lots of people said Hyperdimension Neptunia was crap but that too wasn't so bad. Maybe a little tedious near the end but I've played oldschool RPG's and that's nothing new to me. Also liked Enslaved and Madworld for what they offered.
In short I can look at a game or review and determine whether it's actually a poor game or just poorly reviewed. I was a fan of Ico, Shadow of the Colossus, and Psychonauts before they became popular.
