I don't see people bragging anywhere lately and if ppl bother you, flame people, not a guy who code for fun from time to time. If acis would be a 999euro paid project then yeah, it would be complete long time ago / you could blame and flame Tk for doing nothing. But currently, you shouldn't say anything.
Wait what? 'Failed so hard', what does that mean and what does aCis have in common. It did not 'fail' because of the pack, just lack of players.
The pack, nor the dev(s) are guilty of failure of a (empty) server. You could say that when tons of people come and the server crash without any reason or has ultimate bugs.
There were several servers / projects with great devs which, as you say, 'failed'. No matter the chronicle, Interlude or H5.
He's on a trip to Scotland atm, so he won't answer
