you dont know that
I've played every rpg game on blockland over the last 9 years and in almost all of them it was apparent that the devs focused more on meaningless content bloating like 200 variants of the same dumb enemy and also some stupid leveling up system where every kill rewards you an arbitrary number of experience which helps you deal an arbitrary amount of damage to some arbitrary amount of identical enemies.
Theres no way one human can make a remotely interesting rpg game. The scope is way over their head- character and story design needs a year of writing to be passable and for the most part rpg mechanics already just have the bar set too low, so it's not like any rpg game made by one person can achieve any sort of quality
