If you could erase the memory and start over with one game, what would it be?

Final Fantasy IX, getting to play that again without knowing a thing would be the most wonderfull thing ever.
Maybe Oblivion or Klonoa though. I could think about this for hours and I'd probably come out with more games than just those three.

 

[The_Lost_King]

Maybe Dragon Age: Origins or Mass Effect 3(with a note to stop playing once you talk to the Illusive Man for the last time). Yeah that would be nice .

I would love to do that for Portal and Portal 2. Trying to figure out the puzzles was a bulk of the fun for me. I still replay the games from time t time, but now that I remember some of the puzzles pretty well, I get through them faster, meaning that the fun is short-lived.

Majora's Mask, and not just because it's my favourite Zelda game, but also because it's the most different of the Zelda games and I think it'd be interesting to experience it again.

I'd have to say Bioshock.
Favorite game of all time, and re-experiencing the plot twist with genuine surprise is an experience that I agree to in a heartbeat.

Without a doubt, Deadly Premonition.
It's a great game, it's just that it has very little replay value.
You see, on the first playthrough I wasn't bothered by the clunky combat or occasionally shoddy visuals. I was so engrossed in the story and characters that I didn't notice. In the ridiculously long driving sections, I'd often ponder who the killer really was, and I was genuinely stumped. I usually figure these things out, but I couldn't with Deadly Premonition.
The whole plot was brilliantly written, and as a Twin Peaks fan I loved all of the little shoutouts. It's a shame that the magic isn't as powerful the second time around.

Oh, and Bioshock would be good with that, becuase it also had a great plot twist. It was like the Polito/SHODAN thing but doubled.

Actually, if ANYTHING, I'd love to have read Dr. Jekyll and Mr. Hyde without any prior knowledge of it. Just think about how shocking the whole "Jekyll and Hyde are the same man" plot twist would be if you didn't already know it. Unfortunately, thanks to, well, everything, it's about as shocking as the assasination of Julius Caesar (in the play, that is) or the sinking of the Titanic (in the movie, that is)

Heavy Rain, no doubt. That game made me feel things I've never felt while playing a game before. I was actually on the edge of my seat during all the trials. It wasn't until after I beat the game multiple times that I realized that not every scene can play out vastly differently depending on choices or reaction time (the first trial for example). But playing it again with the same emotions as the first time would be awesome.

That or Red Dead Redemption, just because I had the ending spoiled for me about two hours before I finished it.
