with the announcement of magic for the PS3, i was inspired to look up the old microprose MTG PC games. (spells of the ancients, manalink, etc)

has a brief play this afternoon and while its main menu is a bit shit, the rest seems to be pretty awesome.

might have to drag out my old cards and put some decks back together.
