It's a twofer on XBLA this week, with a new puzzle game and an old fighting game. The puzzle game would be Droplitz, which has players twiddling dials and collecting small, "dinky little balls of indeterminate stuff." We can't help but be reminded a bit of Pipe Mania. Keep in mind that Droplitz is a single-player game only, with the full game running 800.
The second game is Garou: Mark of the Wolves, also known as Fatal Fury: Mark of the Wolves, which was announced for XBLA by SNK late last week. The game is a port of the original arcade title -- also remembered as one of the last good Dreamcast games -- and features online play for two players. It can be yours for 800.
