I also picked up Arx Fatalis via Steam last weekend as I failed to buy it when it was out in retail. I like it better than their other recent game, Dark Messiah, which I picked up last week. That said, it's an OK game, not great, and I'm glad that I didn't buy it when it was brand new and likely $50...
Even for a 2002 game the graphics are just so-so and pretty dark.
Combat has been pretty cheesey so far.
The default control scheme that shipped with the Steam version was ENTIRELY unuseable to me, requiring a great deal of reconfiguration. (It was almost as bad as Gothic 1 & 2 control schemes, but at least the French figured out what a mouse was for.)
Apparently, no dialog options at all.
The draw the runes magic system wasn't a brilliant idea, IOW they'd been better off with Dungeon Master's string the series of runes together system.
It's been more fun than DM so far, but I've got a feeling that it's going to be short, and fairly linear. Loot's been pretty heavy I've found more potentially saleable items(mostly weapons) than I've room for, TONs of food items, about 1k(!) gp already and I've just hit Arx(maybe prices will be high as the only thing to buy so far that I've found are mugs of ale at the tavern for 2gp), setting is nice but too constantly dark and drab, etc.
Beyond that I still haven't really figured out sneaking, but I still need to read the manual which I had to get from replacementdocs as the Steam version doesn't appear to come with a manual of ANY sort! Not nearly as environmentally interactive as I had expected so far, considering that from what I'd read elsewhere people kept mentioning that. Well worth $10 though considering other RPG "choices" ATM, but if you don't have Morrowind GotY, Neverwinter Nights Diamond, or Gothic 2 Gold(similar age) I'd go for one of those first as so far it seems like they're just FAR better games than Arx.
[EDIT]
As to a comparison to UU, don't even bother as, again, so far, both UUs were FAR better games as well...
