It's a very slow game to stream, and suffers from a high learning curve and queuing.

A couple of us used to stream it, and it got a decent response but the community was much more lively at the time, and it fizzled out relatively fast just because the game is so slow and none of us were particularly great at streaming.

It much more suits an editted format that showcases specific parts; see concon's youtube series or all the edits people used to do

EDIT: there's also a weird gap in the age range that play this game, by the feels of it. Lots of young teens playing the game, and then a lot of us sticking around the forums have been here 8+ years and are hitting our 20's. Probably makes for a weird mix for a stream cos you're streaming for one audience or the other, and neither group is probably big enough to make it long term worth.
