looks so amazing, only one question. Is most of classes/races in the game?
Not really. The available races are human, mul and half-elf. The classes are fighter, cleric and wizard but wizards don't have to memorize individual spells, they get a number of spells that they can cast from every level per rest (like in the Dark Sun games).
The game is still very good despite the limited selection of races and classes. As for how the wizard works, I don't mind this approach. I never particularly enjoyed choosing which spells to memorize individually before resting.
