To all saying Blockland is toxic, that's like complaining Halo Combat EV is violent. There are far better examples of toxicity among video game playerbases. (Cough cough, Roblox.)
Yes, please do return to Blockland. So long as you treat people with decency, you'll find a few shining stars out there.
And for everyone else, try not to take the game for granted, it was the pioneer of sand box building games, with a unique and charming visual and audio style, and an early example of a video game with a modding community. Don't jump ship on a whim. Also, the more you shy players away from returning the dead-er it gets.
So don't rallyabout Blockland being dead if you're still lurking on the forums with a pristrine BL_ID sitting there begging to be used. If everyone in the "Blockland is dead" ship holding an account joined in on a servers right now the game would be booming, but they're too busy fulfilling their own prophecy. It'd be even better if they tried looking into solutions for the problems they complained about, like the in game physics...
