To add to FromTheShadows's comment, CRPGs usually emphasize building unique characters through stats points allocation and skill development over time. Your unique build defines how you "roleplay" in the game. (or inversely, you decide how you want to roleplay and build the character around that) Some people just min-max and try to find the most optimal build for combat.

Technically Skyrim is still a CRPG but it streamlines to the point that it drastically veers away from that original idea and becomes more like a first-person adventure game. (or even an FPS with spells) You don't have to worry about stats building at all.

The CRPG Addict has a blog series where the author is trying to play every CRPG made and review them. If you like those kinds of games it's a good way to find new ones to play.
