Kena is a fantastic game that deserves your money.
Speaking of which, now that I've put a few hours into GotG I realize just how unfair the bad sales are. The game is just great all around and you can tell that a lot of care was put into it. It's polished, has great production values, the writing is hilarious, the campaign seems to be fairly long, it's one of the best single player games in recent memory. I actually feel bad paying $6 for it just 10 months after it launched. Such a shame, it deserved so much better.
