I liked the demo a lot. It comes with Midway Arcade Treasures 2 at EB, which is a good deal. But I already have it, so I'll probably wait for it to hit around $30 before I pick it up.
Well, I got a good deal on it (one of the lucky winner of CheapyD's drawing; wonder when it'll arrive).
If you don't have MAT2, and want it, then the 2-pack is probably the best deal for now. Aside from that, you could wait until EBgames.com has it for $45 used, and then use CAG15, SAVER, and an Edge card to get it for $33.75 shipped. Otherwise, looks like it's $49.99 everywhere, for now.
