This only very superficially resembles Diablo III. Do not compare them.It's so mediocre, they didn't even bother making a video review long enough to mention sounds, music or story. Which we can presume were all subpar, else even a brief mention would probably be heard to justify this somewhat generous 5.0 rating.
I played the demo, and I like R.A.W for what it was. A "Gauntlet" Clone, though not too much has been added to this game since that older series.
I didn't like the enemy swarming: that got annoying, even in the demo. Still, not a terrible game.
It's more like Gauntlet than Diablo. It's nothing new, but a throwback to the earlier days of Action RPGs. Playing on a higher difficulty, however, does make the game far more enjoyable due to the added tension...prepare to die a LOT
