An Alternative to Sittable Chairs
Champions Online has two different sitting animations, /sit and /sitchair. The latter causes your character’s legs to hang down as if they are sitting in a chair, of course. Having these two different animations available (to be manipulated by the player, to make their character use a chair/bench/stool/edge properly, which took a bit of finagling) always made roleplay or taking interesting screenshots look really natural (once you finally got them seated correctly, that is).
Of course, if you use /sitchair while just standing on the ground, your character’s lower legs disappear into the terrain and it looks odd. But that’s not what the emote is for!
Champions Online also had a great variety of possible character body types, from large beast-legged men to thin, fae-like characters. I understand variety in racial appearances is the major issue preventing GW2 from having seating function well, and GW2 runs on a different engine than CO, so the physics and animations work differently.
I’ve always really liked CO’s emotes, though, and I thought their /sitchair should be mentioned as something to look at while we’re on this topic.
I fully support the idea of emote variety!
