sounds like you want to make a hybrid game. part turn based hero combat, and part rpg. IE a rpg with turn based hero combat.
such a game can be done in 2d or 3d or both, and can be web based or not, assuming the web based performance is acceptable.
1. Yes, I do want to make a hybrid. Part Turn based hero combat, part RPG.
2. While I agree, I wish not to make a full fledged RPG world, because I'm an one man army, and would love it if there's a different way I could go about solving my desires for the game.
