why, what was the purpose of this thread then?

Current achievement system is bad and staff can't add proper achievements without developers' interference - and there's only one site dev at the moment (me) but too many other more important features / tools that need to be added / fixed.
We'll eventually get a new system, what you can do in the meanwhile is suggest some good achievements / achievement types. "Win x games in this mod" is pretty simple to add and we already have that (even though they don't work properly), I'm talking about actually fun achievements that don't just rely on farming games.
