STALKER went open source a while back and it was the best thing that happened to that modding community. The only difference is that Blockland is a multiplayer game which introduces its own security issues, and like 1 in 3 blocklanders is a malicious psycho so there’s fewer “reputable sources” for compiled engine mods than there is with STALKER. But we’ve seen it before; going open source would be a huge win for BL and would draw in a significant amount of new players and life, but at no benefit to Badspot, so it won’t happen.
