I think I'd go with.
1.Blinx the time sweeper, such an amazing story, truly timeless gameplay, just about everything you could ever want about a game starring a cat with a vacuum cleaner.
2.Kabuki Warriors, (Also known in japan as Bukkaki Warriors,) Another amazing game, with truly interesting battle mechanics.
3.Greg Hastings tournament Painball. I don't think paintball has ever been this visceral and intense.
What other timeless classics would you suggest SW?
