CRPGs are best when they create atmosphere, immersion, drawing you into the game world, you need a sense of the real/mundane/everyday to keep you grounded in a world full of magic and monsters. Small things like weather and the passing of the day are intrinsic to this and I just cannot fathom how they don't deem it important.
Different people find immersion in different things! For me cinematic dialogue is very important for creating immersion, and for you it is not important. For me day/night cycle and weather are not important but for you they are.
