Just played a Marauder to lvl 15, and I actually really enjoyed it!
Though I was kinda turned off by how much it looked like they copied diablo initially (do health squares or hectagons, but for christ sake dont do spheres
), it really grew on me pretty fast.
The game looks incredible and I was able to run it all maxed out @ 1900*1200 with 40 FPS on a laptop (GT 550 GPU) - which is pretty sick when you see how good it looks. Other than being surprisingly beautiful/efficient, it also really had that dark oldschool diablo feel to it which is awesome.
I really like how they did their potion system and the passive skill tree is a awesome aswell (could've been a bit less crazy tho). But I really like the fact that you use all your skill poins on passive while leveling your abilities by themselves.
The best thing about the game tho is that the developers are listening, responding to the players. There was pretty much constantly an employee in the general chat responding to the players questions/suggestions. And it seemed like they were working on pretty much all the major things I thought they could improve (voice dialogue, ability to zoom out further).
The only thing I wasn't a huge fan of was the classes and how they looked, but still it's definately something I'm gonna give a go when it comes to and see how the finished product fares against D3.
