I know it's already been said, but Ocarina of Time is the greatest game ever made.
1. great soundtrack: all the legend of zelda games do
2. great gameplay (bosses, weapons, etc)
3. just the right amount of glitches: any great game HAS to have a glitch or two, i'ts awesome when, after hours and hours of play, something goes horribly wrong in a hillarious way. ie. i killed a stalchild once, but instead of dissolving in a puff of green smoke, he fell apart halfway and started floating off backwards really fast and all my temporary items dissappeared
