My very 1st programming experience was on this baby as a ~10yo kid.

Still remember how instane it felt.
I remember that when constructing the truck I forgot to add in some gears so the claws didn't rise properly and I had to dissasemble the entire cabin again: my dad almost had to force me to do it because I was constructing it for so long that I was totaly tired and just wanted to be done with the damn thing.
