So basically, Final Fantasy, Neverwinter Nights single-player campaign, any jRPG and similar games are not RPGs? Because there's no role playing in there, just advancing through the storyline while increasing your stats.
In any of the above games, you play the role of a character or party with their own skills and stats, and it's your job to play out their skills strategically to win. That's an RP
G. MMORPGs feature player interaction so they have RP added on top, which makes them more interesting. Multiplayer RPGs like SS13 also require RP in order to be more fun. But you can win the game by just having the Wiki open and chatting in shorthand. Still the same game but less fun.
The word has been defamed. Mass Effect, Fallout 3, all those, are not RPGs. They are just games where you play as a character and have stats.
Funny, because the stats are just what makes these games a little bit more like an RPG and not just an action game. They are indeed not RPGs though. Because the player himself has to be skilled at shooting and dodging, it is just an action game with stats.
If it's about player skill, it's not an RPG, it's an action/puzzle/adventure game with role playing. Even though the role play features way more heavily than the other elements, the term RPG does not apply.
A role playing game is about playing the role of a character and applying that character's skills appropriately, independent of your own skills other than strategy.
Role play is making the above character believable and interesting towards your fellow players.
Then what sets an RPG apart from a strategy game? Not much, mostly the focus on a single character/small party, the story and the character development.
RPGs with stats have existed from the very beginning. In fact, checking Wikipedia's history on RPGs (
http://en.wikipedia.org/wiki/History_of_role-playing_games) actual roleplay is hardly mentioned. These games have been the first use of the term "RPG", and are obviously heavily based on stats.
So please don't defame the word RPG by saying stats are not needed. Stats have been and will be an integral part of the RPG experience. RP itself is an entirely different concept which happens to make RPGs more interesting and involving.
