If you don’t need super fancy graphics and don’t mind some walls of text, both of Owlcat’s Pathfinder games, Kingmaker and Wrath of the Righteous, are absurdly intricate character builders. There are probably 20 classes, close to 100 subclasses? You can generally mix and match them as you wish other than not being able to take two sublasses of the same class.

Both games also include a roguelike mode DLC that can be played separate from the main campaign, which are mostly combat and great for testing new builds.

Do yourself a favor and install the mods that let you define your standard buff set and cast it as a macro. Otherwise you’re gonna spend a lot of time manual buffing between fights.
