should I buy an alt just to use the forums

I checked recently that you can use a Steam id instead of a BL key for the forums. Since I can just host dedicated servers (if I ever figure it out) on my main ID, I don't need that ability on any alt I get unless I lose the main ID, which is highly unlikely.

So give it a few weeks, and Steam Blockland will prob be atleast 50% cheaper due to summer sales

Might want to consider buying the 4 pack. I've wanted to buy that during multiple sales but you can't if you already have Blockland in your Steam library
