Hey, I don't mean to be annoying and bring up other games, but if you are into action rpg's, crusade of destiny is only .99 now usually 4.99. Just puttin it out there.
geoSpark is great for pick up and play and an update with achievements and a few other elements is on the way as well. Best thing about the game is the soundtrack, though. Really, I boot the game up sometimes just to hear the track, which will be extended in the near future, so that is something to look forward to as well. Haven't picked up Cross Fingers yet, but mobigames is about quality, so you can't go wrong with picking this up as well. I think they just released a lite version, so check that out. Matter of fact, I will purchase this as well right now - I'm not sure why I have not yet.
