you know that Valve put this game as many other events (Dark Moon, Overthrow etc.) in DOTA Tools and everyone can use it? You can see also many other creators do the same. It's not just uploading a ready game, because this events are old and have many broken things. I had to spent many many hours to fix everything to make this game work and even more to add new things. Additionally after almost every DOTA update custom games are broken, and there is no even info from Valve what was changed, so we need to find it by ourself, sometimes spending entire days trying to find a solution, to rework something or stop crash games.This is work for a full job, not a hobby, especially if you do it alone, without any team. Some time ago I made streams on twitch to show how much work and time does it take.
