Depends on what you're looking for. Shantae and the Pirate's Curse is a great metroidvania platformer, Shadowrun Hongkong if you want to experience a cyberpunk+fantasy RPG, Rebel Galaxy for a space game with some trading and naval-style combat (ships don't move in up/down directions), Van Helsing for a diablo-like experience

I'm also seeing Hyperdimension Neptunia on the sale, though I have no clue if it's any good. I always get baffled by the amount of games in that series
