what are the best fps and rpg titles for android w/ controller support?

Hey just wanted to know what the best fps and rpgs for android? I've just ordered the M8S Android TV Box KODI Amlogic S812 Quad Core 2gb 4K Streaming Media Player from Amazon and wanted to know when I get it what games you think I can install on it. I have Vice City and San Andreas already to install on the Android box, but I'd love to know what games are out there for android. Would like to try to stay away from pay to play type games, so mainly looking for games that can be finished with out having to shell out cash, just to complete the game. Also some multiplayer games would be nice! thanks:yup::lol:
