Really agree with the CGC remakes - sounds like it will be one pin (for now...) and you want something with enough depth to not get too stale and not so much depth as to be too long of a game. I have a Getaway and while I love it as a quick play game, it would get really old really quick if that was my only pin. My order of preference for a one pin collection CGC remake:
1. Cactus Canyon,
2. Monster Bash,
3. Attack from Mars,
4. Medieval Madness.
