Thanks for replying. For number 1, if your Int is higher than str and can't do physical combat, they can instead do magical combat like a mage. You focus on Vit, you become a tank and such.
About the number 2, it means you get skills based on your activities. Example: You like to do stealthy combat, then you have a high chance to get skills related to it. Stats will also be a factor in some skills. When you reach a certain requirement, your race evolves which also boosts stats. (Ex: Goblin> Hobgoblin> Ogre)
Number 3 is kind of the same with number 2. You don't choose class, you get class based on your gameplay which also upgrade/evolve. Titles can have some authority over something. Like a noble managing a region, etc..
Though, all of this is just an idea of mine for now, as I'm still learning to code. What i want to know is if this is something that is actually doable if someone knows how to code.
Sorry for confusion. English is not my native language.
