I think a lot of people are unfair when they review this game, mostly because they review it thinking of it like a Diablo clone. In all honesty, R.A.W. is more of a Gauntlet clone, but with some more RPG elements thrown in.
The game is mostly a slogfest. Kill enemies, maybe do a random quest, reach the next area. Most likely get one experience level on the way (there is an experience cap per area and once that has been reached you barely get any experience).
Is this a problem? Not really. Sure, the game might feel sluggish at times, but overall it actually keeps on going pretty well. And except for the beginning when I didn't use the compass enough I never really got stuck anywhere. (Oh, and there's no map in the game, only a compass which shows the general direction you're supposed to go.)
Overall: Not a bad game. Not the best game in the genre, definitely not the worst. Just don't go in hoping to get a Diablo game, then you'll be disappointed.
