In no particular order:
1.) Star Wars: Jedi Power Battles (most bugs ever in one game, and they even made a sequel)
2.) Legend of Zelda II (ugh, why did they try to be all RPG about it, it was a pain to play)
3.) Pokemon Stadium (Ok, the game was NOT ready to move to a bigger console yet, it was basically playing the game boy on the bigger TV, not very exciting, and hey some of those little Pokemon games are actually kind of fun but the Stadium games were pretty dull and the mini games sucked)
4.) Final Fantasy VII (Ok, I know I'll get shot for this one.. but the story absolutely bored me, there was so much potential for it to be great but I just couldn't get into it at all)
5.) Halo ( It wasn't that fun, everyone made it out to be the greatest game to play with friends on campus but in reality it was dull and there are much better shoot-your-friends games out there)
6.) Star Wars: Jedi Starfighter ( I think there was a normal Starfighter game and then Jedi was suppose to be basically "Jedi in space" and other than the fact that I got to play my favourite Star Wars character [Adi Gallia] it was too easy and not overly exciting in terms of story )
7.) Star Wars Galaxies: An Empire Divided and its expansion packs ( Bleh..we never got what we wanted, the dream died )
8.) Chrono Trigger ( Like FFVII I'll be shot but maybe it's because I played this after it had been rereleased for playstation and so many good RPGs had came out since the days of the SNES with intricate stories and characters.. Chrono Trigger seemed so dry to me in terms of story and character development )
9.) Yoshi's Story ( Ugh, I was introduced to this while babysitting ages ago.. I can't even tell you how horrid it was, maybe I am too old to appreciate it )
10.) Asteroids ( because I can't think of anything else.. )
Really it is hard for me to think of bad games since I only play games I have a high interest in and generally research them out before buying them since I can't normally afford games when they first come out anyway. And yes I play too many Star Wars games, just as I read too many Star Wars novels, or visit Star Wars websites, or..you get the picture
