I guess if you play Pokemon, you can try out PokeFarm Q, a game like FlightRising and such. You can find it over here. There's also a FPS f2p game called Paladins, made by Hi-Rez Studios, the creators of Smite. You can't play it on Mac, though. Only Windows. You can find it on steam and here. My username's Turtleawe on both games, if you wish to know, boop.
