Back in 2010, a week or so before Halloween, Double Fine Productions released Costume Quest. Somewhere between then and a month or two ago, I bought it on XBLA, and I finally got around to actually playing it about a week ago. It's a cute, fun little game, and I enjoyed it.
It's basically a light RPG-type game, where you run around neighborhoods trick-or-treating houses, collecting candy, costumes, and battle stamps (which improve your abilities in combat). Encounters with monsters are the meat of the game and trigger a sequence where the cute cartoon children and silly monsters morph into giants who do battle over the town in a turn-based RPG style. It kind of reminds me of that episode of South Park where the kids morph into anime characters and battle each other.
The cartoon graphics are crisp and colorful, and the sound design is simple, but does all the appropriate things. Controls are easy. Overall, it's a shorter, but quality title - the quality of which I've come to expect from Double Fine.
If you haven't played Costume Quest yet, I'd recommend it. Maybe save it as a little Halloween treat for later this year.
