Someone gave me a $25 google play card. I pretty much just use my S4 for a phone and camera.... No clue on Android gaming.
Xcom:EW is fantastic (haven't played the new version since I don't have a supported device) if that's something you're interested in.
I recently picked up a Nexus 7 and I'm surprised by the amount of rpg's and strategy games available that are not on iOS. Definitely more of a Wild West I apps but it was worth buying into. Theses aren't on iOS but I figured I'd share. Games I've been liking: 1Quest (excellent dungeon crawl with RL elements) Rogues Tale Tales of Illyria (Oregon Trail/Rpg/strategy) Crystal Story (1 & 2 - Turn-based RPG) Delver (excellent looking first person dungeon crawl with permadeath) Pirate Dawn (cool open world pirate game - kinda like assassins creed but top down perspective) Gravebound (just a cool Roguelike)
