1) anything with Grand Theft Auto in the title
explanation: the whole "I just had sex with a hooker then ran over her in the car we had sex in and stole my money back!" thing gets old after the 10th or so time, and really what more is there to the game?

2) anything with Tomb Raider in the title
explanation: the series is a total joke now (as it should be), but in its heyday people made a HUGE fuss over it and Lara Croft was considered "hottest game gurl EVAR!" to a point that still makes my skin crawl.

3) Final Fantasy VII
explanation: Maybe it's just the iconoclast in me, but I think that people make a bigger deal out of this game than they ought to. Contrary to popular belief, there was nothing that was technically ground breaking. Even in a historical context, there were games with far better graphics at that point. Square themselves even admitted it was rushed. I personally enjoy playing "count the pixels" on some of the backgrounds. Plus which I wasn't all that wild about the story. This game was actually the whole reason that RPGs and the Playstation became so wildly popular, so it's really not hard to call it overhyped.

4) Halo
explanation: OMG IT HAS TEH BUGGY!!!!11 It's yet another console FPS. Who cares? FPSs on consoles have horrible controls by definition, and this is no exception. Poor Bungie really ruined their reputation with this one. Not that Oni was anything spectacular...

5) Pitfall
explanation: I dunno, was this game really all that revolutionary? It was a decently made game and all but it just didn't have much to offer. After you've jumped over your 10th snake you start wishing you could punch things or shoot things. Even Adventure lets you pick up a sword for 5 seconds. Sheesh.
