Ah.. Lego. Good times.
I had this big, black freaky robot thing that had a detachable head and you could put a little dude in it. I also had some aquaraider shark submarine thingie. And some other random spaceships that lasted a few days before I broke them apart.
Then I had a bionicle set, when they were new, these wierd small chubby thingies, don't remember what they were called. You could like fold them together to a ball. I had all of them. Making some kind of fort with Lego then conquering it with some dudes was also fun.
I don't play with Lego anymore nowadays. It's not digital enough for me. Maybe those mindstorm thingies, make some robot. Wait, I would go nuts (remember me and my bot in #lrs? hehe)
