So I came across this game Card Hunter while looking for simple games to pass the time with on my weak laptop. So far it is entertaining, combining table top simple D&D board game style with some cards to use for moves and abilities. With a silly little brother versus older brother arguments over how to be a GM tossed in between adventures.
It has leveling and upgrades for your heroes. A lot of cash grab available for upgrades, but so far I have not seen a need to use it. It has a single player campaign and multiplayer PvP so far.
