My main evaluation criteria for RPGs in the quality of grass. If a game has nice meadows or fields, it is worth playing. NWN2 has a passable quality of grass. A bit better than average from that time.
HOWEVER. It has absolutely lovely fairy tale-like night skybox full of shimmering stars. Therefore, I have to recommend even the otherwise overwrought and undercooked OC of NWN2.
You wanna pass some of that grass my way?
