I'm not a lego collector, but my friend the lego collector bought me some Halo Megabloks and now I'm sort of stuck collecting them. I had almost all of them (not the $40 Scorpion, for which I've been trying to score a deal on ebay) and then they went and released a bunch new sets.

And I hate to say it, but they are awesome. And I must have them.
