I bought this on GoG at least a year ago... as Cutter said, it's a little underwhelming. Your mileage may vary, but I have yet to finish it.
The combat is okay, the storyline is okay. the NPCs are somewhat good (so far), but ... I don't know, it's not really engaging and fun to me. Disclaimer: my playthrough is/was as low murder as possible, aside from straight chaotic evil type enemies, I have not killed any NPCs at all. Your powers are much weaker as a result.
