The 'rewind' option was incredibly helpful in a lot of games. It existed in Total Overdose, the Prince of Persia series, GRID, DiRT, etc. These games were pretty fun and the ability was well executed. Would you want to see this ability in more games? I'd like to see it in GTA and similar games. Some RC missions and shooting missions in GTA games are pretty hard and it'd be cool if there was a rewind option so that I could try it again.
