So I was reading the thread about Alpha Protocol and noticed how many people were talking about leveling up. So a question regarding RPGs and leveling up came into my mind: Is it necessary for an RPGs to have a leveling system at all? Shouldnt the focus in an RPG be on roleplaying instad of just the leveling up? In my opinion one can still call a game that focuses on roleplaying an RPG if it has no leveling. What are your opinions?
