Honestly for the budget price, it's more acceptable however. I like to hold onto my games, and memory can corrupt. Also there will eventually be a point where the game may not be hosted any longer and then I've got a 20$ piece of paper.
I'm adamantly adverse to digital distribution, I will not exceed a 10$ purchase for a download-able game. I've yet to purchase a single thing on Xboxlive arcade or any game add-ons, though I've purchased a few VC titles PAIN(when it was on sale) and will purchase Final Fantasy 4 on Wii ware. Even that much is kind of pushing it for me though, I'm not paying retail price, even at budget, for a game that I don't technically have. Especially when it doesn't save me space, I still get the case. Just put the damn physical copy in there..
