Without mods it sure is a Troika game through and through - as in, a big mess. Personally, I'd say it's the weakest from their catalogue, too. They replicated the tabletop module very accurately, but the amount of combat is just too much at some point. The entire latter 2/3rds of the game are a huge dungeon crawl that has quite a lot of variability (even from a role-playing standpoint!) depending on how you approach it, but the primary activity is still fighting, fighting, fighting.

It's almost like it sucked all the metaphorical well-implemented combat essence out of Arcanum and Bloodlines (so their combat is awful) but didn't have the traditional strengths of Troika games in turn. It's still an enjoyable ride if you like 3/3.5e, as it actually implements about as much as they could carry over mechanically. It does have a level cap of 10 (without mods) and no prestige classes, though, and the UI is, for the most part, horrendous (something Troika is also infamous for).
