well, games like Dungeon Hunter 5 or Vainglory for example.
Bastion looks great.
Beast Quest might not have the best graphic, but is also a very cool one.
Rayman Adventures. Awesome graphics
Fantasy War Tactics is very close to the well known Final Fantasy Tactics.
Alto is a very cool looking laid back game.
Bomb Squad is mad fun with up to 8 players.
Crashlands is a game for fans of Don't starve
There's also a sh*tload of shooters and racers with really impressive graphics.
