First of all, thanks for all the replies, comments, new ideas!
I used the forum search before posting to see if such a topic already exists and those three I found were years old and for canyon

I don't think it would be really necessary to both place blocks at the same time but driving it at the same time would be great. Also if the other one just could have a look around and bring in tips and ideas would already be a huge revlution

I think so too, might be better only one player is building at a time.
But anyways,

for yoshi's try and his work! Hope he keeps on working on it or we can maybe see such an awesome thing made by nadeo.
