Oooh, that was a terrible game... good thing I didn't buy it. my bro did.

I usually thought out my game purchases before hand, and saved me alot of time selling games. One game that was horrible was YU-Ki-OH: Kingdom something?(Not sure the name)
I wanted a game that played like the actually card game, but I got stuck with this crappy real time stregy RPG element like game...

EDIT: This is the one... "Yugioh: The Falsebound Kingdom

Maybe Ultima VIII:Pagan? It was the first RPG I played, and the last one too, actually I think it may be the reason why I never play RPGs.

Before playing it, I was reading the manual and I thought it was awesome, but then I couldn't stand playing it.

 Haha, i thought i was the only person who bough this game and it was the only game that i ever returned.  I bought it without reading any review because i had recently played the PC version which was awesome for the time.  I thought to myself, same game and i'll get to play it with a better controller, boy was i wrong.  EVERYTHING about the game sucked and it was nothing like the PC version.

the 5.9 gamespot gave it was really generous, cant remember if I bought it or my parents but it was a terrible game. story was half way interesting but the battles (and the ramifications of someone dieing in battle being permanently dead really killed the game)

hour of vicotry for xbox 360 (when i still had one), or spyro for ps2. seriously i rented hour of vicotry and it was horrible, but it had easy achievements. the melee was stronger than bullet hits, and it has no ww2 storyline. the most exciting thing you do is rescue a danish professer from a swedish jail. spyro, i just got turned off by it.

and to no surprise, i went to gamespot after and they both recieved scores of under 3.

Meteos

Impossible Mission for the SNES, one hit and you're dead which made the game... IMPOSSIBLE!

this one... almost broke my N64 

Capcom vs SNK 2 for the Gamecube. I love the game, but for some reason it has a low score almost everywhere :( ???
