It's a great deal, but I wonder about something. Am I the only one who sees a great bargain like this and grinds his teeth a bit when he realizes that he purchased all four of these games, in a box, when they were brand new. They cost a LOT more then!
If everyone waited until the games were dirt cheap, you wouldn't see any more commercially produced games.
If you enjoy the games, don't regret having paid a bit more to support development of future games.
