My first choice would be...

Construx





I think they proved the market for more complex legos. And when Lego Group saw what could be done, they took the opportunity, and Construx couldn't compete with the Lego name and more modular nature of the base pieces. Plus, you can program legos with a computer now.  Nevertheless, Construx were more geared (no pun intended) to different types of vehicles and more durable works than legos of the day (my lego cars would always fall apart at the slightest provocation.) And they had glow in the dark parts!

Lady Lovely Locks as long as she doesn't look like she's part Bratz or something.

I had this tank like vehicle that you could program to move and then send it out and it would follow your instructions that you put in to it. Iid like to see something like that again.

I found it! I spent hours playing with this thing.

Ha, that looks like a VHS tape rewinder crossed with KITT or something on Star Trek.

I want one.

I had one of these many many moons ago and I would like to see it reprod. I played a shooting game that was with it for soooooo many hours.

WTH? It looks like a homemade bomb with a trigger detonator. Ha!

- M.U.S.C.L.E.
- Rock & Bugs & Things (Toyfinity actually has the rights now and are releasing a new line of mordles this summer)
- Madballs (a completely new wave of characters)
- GoBots/Rocklords (a classics line would be awesome!)
- Robo Force (Toyfinity also now has the rights to Robo Force)

I would love to see a new line of M.U.S.C.L.E. figures, made in the classic style. But, in addition, I would like to see them manufacture a 5" or 6" line with some articulation.
