Technically, plural for Lego is still Lego, but in 33 years of my life, I think I've pulled that off, maybe, five times. So, we shall refer to lots of Lego as Legos.
The Admiral made a comment to me not too long ago that I played with Legos right up through high school, and I was all "oh, that's crazy, no I didn't."
But, everytime KareBear had kids in the house, she'd haul out my Legos, and I'd find myself sitting on the ground assembling Legos into space ships right through graduation.
I understand there are adult collectors of Legos who make magnificent Lego sculptures, but I find them sort of cost-prohibitive, and I threw in with Action Figures v. Legos long ago (I have shelves and shelves of Super Friends, for those of you who don't know). And moving Legos is a total pain. But I sort of miss sitting on the floor and trying to build an intergalactic star cruiser.

We never had Legos like some other families who would roll out these amazing piles of pieces, but we had a pretty good set up. I would make whatever the kit suggested once or twice, and then make my own stuff. That always seemed the point to me... to follow the basic instructions so you could understand how it fit together, and then go off and do your own thing with the parts.
With Star Wars, Batman and Indiana Jones Legos out there these days, I bet kids have a field day. Add in the standard moon-scapes, rockets ships, airports, etc... Well, it's a slippery slope before you're living in a house constructed on tiny pieces of plastic.
And some of the other options... I mean, look... Build the Taj Mahal from Lego. How cool is that? Or the Death Star?
This set called "Star Justice" is pretty close to the kind of stuff I liked as a kid. But, look how totally expensive that is... Man, I feel for you parents trying to properly outfit your kids with Legos. No wonder The Admiral and KareBear were always working so hard... to keep us knee deep in Legos, it seems.
Anyway, no Legos for me. I don't think Jamie wants a million plastic pieces scattered everywhere. But whenever I see ads in print or on TV, I do start thinking of what you could build with the pieces to the new sets...
