Evil Genius is this week's addition to gaming service GameTap, so subscribers can play Elixir Studios' good-to-be-bad RTS game. There's a new free game this week as well, or actually an episode, as The Master Thief offers one of the episodes from American McGee's Grimm, free to play just in time for Halloween (the attention can't hurt, it looks like the episode got one hour of total play on the service last month). They also announce next week's new subscriber game will be Still Life 2, and that Astro Fury and Battlestations Midway are among the growing list of games they have upgraded for 64-bit compatibility.
