Ehh...I can't really narrow it down to one game, more the series. I'd have to go with the Final Fantasy series. These games are great; good storyline, gameplay varies from game to game, and the fact that there is hours after hours of things to do on each one makes them awesome. I would have to say they lost their magic after X, though. They became..well...just not as fun :T
Royal you just reminded me....I have FF7 on my computer at the final boss fight. It's been there for months. I must beat it tonight! I feel slightly ashamed that I never got into the DQ series. It's not a case of lack of interest, it's just i can never find a copy of the early versions.Ah well..the hunt goes on!
Pokemon~! GOTTA CATCH THEM ALL. DOOT DOOT DOOT! THROW THEM BALLS AND CATCH THEM IN- ._. Shane Dawson fan. Nuff said.
Eh... Final Fantasy started going downhill in FF 126:the next 200chapters of idea stealing... Oh sorry I forgot I'm from the future jks ff is an ok game but seriously... HOW MANY FRIKEN GAMES R THEY GONNA MAKE?!?
