I hope so. I think there's a lot Blockland could use. I think it would be great to integrate the duplicator/fillcan as default, add in some of the features of Glass/RTB (mainly the detailed server settings), do some quality-of-life improvements like add in environmental presets... There's definitely a lot of stuff that could be done. I think it would be beneficial to grow the playerbase too. Someone coming off the Steam store to play Blockland 100% default might miss a lot of the things we take for granted.
I don't really anticipate a major content update again, unless the tide changes for Badspot or something. We've gotten intermittent small changes for years so who knows! Brickadia really looks promising though.
