I grew up playing Titan Quest, my most recent playthrough was just recently and I decided to pick up Grim Dawn on sale because it was made by the same developers. Holy crap, it's the most fun I've had in an isometric ARPG! Things I wished were in Titan Quest as QoL improvements are native to this game, and it has all the fun of class-combining and equipment management that was good in older games without the boring or annoying parts. Grim Dawn takes the fun parts of PoE and Diablo and expands & condences them where needed to fit perfectly.
