Mmm, the game is great in general, although the crappy engine takes the whole game down a few notches. I'm playing it now, and the only problems I encounter are more or less the crashing bugs (died 3 times on me yesterday...). I'm wondering if there'll be any sort of official addons and bonus bits.
And yes, it IS an FPSRPG, although the engine makes it suck on the FPS fron in such a way it's near-impossible to play without making use of VATS. I for one feel that is Van Buren, but on a crappy engine... Hopefully the game hasn't been rushed to make the release date. (KOTOR2 ring a bell?)
