If you do not own Braid, Crash Commando, Echochrome II, Gotham City Imposters, Plants Vs Zombies, any Red Faction, Super Stardust HD, Tokyo Jungle or even Spyro this is a great deal.
Hell Jurassic Park and Back to the future are worth a buck especially if your a fan of the movies.
Basically this is why PS rules and well the other guys not so much.
