Spent some time researching this game. Looks like PoE inside of the D3 engine, which is something that I am very excited about. But it is all about execution; I'm not sure the $20 price tag is enough money to execute it properly. Very ambitious game; probably should have charged $30-40. Haven't found any information regarding any plans for MTX.
I picked it up. It is still a little (well a lot) rough around the edges but definitely has a lot of potential. The skill 'wheel' is amazing, the ability to mix and match to build your own class is even better than Grim Dawns, which is saying something, and the game is definitely the best looking arpg to date. That said, the animation and movement is still hitchey as hell, often locking up all together, the monster path-finding is bad enough as to basically be considered not even there and many of the skills and key features they talked about in their kickstarter from a year or so back (was called Umbra or something like that then) are still just road-map items.
Overall though, definitely enough there to make it worth watching.. with another 9-12 months of development it could easily be an amazing arpg.
I played it not long after they released it. It was extremely rough, returned it after 45 minutes or so, but I still watch it. I'm totally down if they get it polished some day, the graphics and ideas are great.
