True, I should have specified 'on the games they're actually focusing on', I just tend to think of that as more of a 'business practices' problem with them. Valve's weird flat structure model and people waltzing away from any project that loses momentum has periodically trainwrecked TF2, but it also outright killed Artifact and Underlords and any of the six million dead Steam initiatives through the years.

Of course, if you look at TF2 as an example here - yet again, it's the enforcement problem, isn't it? The whole process only works if you're investing in it and someone's at the wheel. You can't just engineer it away.
