Implying that only turn-based games can be called RPG's is... kind of archaic, yeah?
Kinda yes kinda no.
Bit of a parallel example here.
-Say I enjoy playing Tabletop RPGs about Space Marines.
-I get invited to play a game.
-Turns out the game is at a Laser Tag arena with 'HP' built into the sensor armor and your light guns have different effects based on a pre-selected class to mimic the system.
-I'm going to be disappointed.
Yes, it's basically the same game in terms of what's happening.
Yes, it's basically got the framework of the game I wanted to play.
Yes, in it's own right, this game is fun.
But that's not what I want when I'm looking for a Tabletop
I want to sit down, casually chat with friends, roll dice, write things down with paper and pencil. Not running around in a glowy cage shooting 'real' weapons. That's LARPing, not Tabletoping.
So, when I look for an RPG
I look generally for a turn based experience. There are some exceptions but the line becomes really really muddled at times. I.E: With an ARPG I want a heavier emphasis on meaningful, tactical combat that just happens to execute it's movements in real time; not a Beat 'Em Up/Action hybrid that calls itself a RPG just because it makes the HP and Damage numbers visible. This is just personal perception here. I know full well the industry/public in general doesn't operate by that standard.
