Then again it all depends on how the lack of a day / night cycle will be implemented. A lot of RPG games don't have a day / night cycle, for example Vampire the Masquarade : Bloodlines which despite it faults is an excellent RPG.
That's true but for a valid reason: it would have been incredibly tedious to wait 8 hours out.
Well there was the sewer system, which they could have made just as elaborate as the overworld had they wanted to. They just chose not to incorporate time as a gameplay mechanic. IMO it would have been quite interesting for a vampire game to have a proper day / night cycle.
Point is, a day / night cycle does not a good role playing game make and vice versa. It's all in the execution.
