Do you like ARPGs? Do you like your Torchlight, PoE, Grim Dawn, D2 and similar? If so, it is worth. Beware, it is beta, endgame is ( still ) not that great, missing variety and more options. Pretty much gear hunt/ gear check in endless grind loop. There are few bugs here and there, nothing major for me.
That being said, i bought this game like 3 months ago, i ONLY play this since ( after 1k hours in PoE and about 200 in Grim Dawn ), now played around 250 hours and still enjoying character creation and different builds, have two chars in endgame ( lvl 100 and 92 ), third on the way. Devs are responsive and take care, community is good. I can‘t wait for 1.0.
