I'm not going to vote since the only one I've really played from the list is Rocket League (and a free weekend of Overwatch, which I didn't like very much). That said, Rocket League is a really good game.
Anyway, moving on to other new IPs, Grim Dawn wins it hands down. I also really like Pillars of Eternity and I probably think it's even a better game, but it didn't quite grab me the way Grim Dawn did, so unfortunately it loses.
