I got it on a retail box a long time ago and I have to say i enjoyed it. It's hack and slash and pretty much linear, but it was fun hack and slash. No inventories, save point system (which I'm not a big fan of, but these were decently placed). A plus for the game is that I actually got to finish it, so it must have something that kept me coming back for more and it's difficulty was tolerable.
You can play with a warrior type of character and once you unlock some of the other character types, you can choose to play with any of those. There's the archer type, the mage type and the demolitions type, who lobs bombs and such. There's a light campaign and a dark campaign, though the characters from light and dark are pretty much the same with different graphics. The game was not original in any way but I had fun with what I got and I didn't expect a masterpiece. I remember the graphics being pretty good indeed.
Hmm... Just typing about the game makes me want to re-install it, since I haven't played it in ages and I've forgotten a lot about it. It's not much of a thinking man's game, except for some puzzles that pretty much consist of the "find the lever" type.
