I really don’t want to be the party crasher, but Lego will not bring back LU with a petition. Mainly for 3 reasons:
1: They already know we want it back, a letter wont change that.
2: Its been dead for quite a few years: they would have brought it back by now.
3: TBH, these emails seem like brush offs. “I will pass it on to the people that worked on LU.” Well, in case you haven’t noticed, almost every single person (excluding the community managers and advertising people) have either been let go or no longer work with Lego.
