2D and 2 1/2D is where old gamers go to retire unless they're ambitious, in that case they go to professional venues and compete for money, and/or, become regulars on some fairly well known gaming related show, like the nerdist, or something more obscure.
the point is we don't expect, or demand much in formats like these, we just spend time honing our non hardcore skills, like mentoring, moderating, and sometimes just goofing around. you can do that in serious gaming too, but there it takes a back seat to actually needing to be able to play something well.
