Not that good of a comparison either. If you say Zelda series of games are RPG's cause you talk to people and collect money you could just as easily say the forum attack system is an RPG cause you talk to people and collect money. You also gain experience and level up, which increases your statistics. their's that word again.....Statistics I would say an RPG is based on stats. plus a good story. It's hard to define what a RPG is exactly, the literal definition is any game where you take control of a role of one of the characters. So I guess Contra could be an RPG too by that definition.
