OK... still harping on the playset issue.

We have a few that could be reworked into something great.
1) Dagobah 2) Mustafar 3) Geonosis 4) Hoth ... and I'm not going to include the Death Star playset because it needs to be totally redone.

1) Repaint the Dagobah playset, include some swamp monsters, perhaps a way to open it up for inside action (it already has a seam)
2) Rework Mustafar. Get rid of the molten meatball idea and instead of flying disks, give us the "raft" that the heroes fought on with a lever to move them along a river of "lava" on one side. Details that look like the movie will sell the product.
3) Geonosis. This one was good, but size is an issue. Short of making the whole thing about 3 times the size (not very feasible) I got no real fixes.
4) Hoth. This just has to be a snowy plastic hill. If you were to make it big enough to have a hangar and a trench, all the better. Collectors would buy a snowy hill that they could put figures and other pieces on. The one that exists is good, but could be expanded. Heck, give is a new piece that will connect to the old one.

We have quite a few pieces of playsets that could be expanded.
**Moisture Vaporator (FINALLY) **Cantina Bar sections **Kamino Platform pieces **Jabba's Dais **Galactic Senate Pod ***new Disney Cantina band Stages **Trash compactor Set pieces ... The list could go on.

My personal wish list
1) The Death Star needs to be redone. Incorporate as many scene elements as possible and make a "Barbies Dreamhouse" type action playset. Make it modular or stackable... I've seen some customs that blew me away. Price points would be tough, but modular is likely the way to go.
2) Sarlacc. This is crying for a playset. Make some bendable tentacles, a movable and opening maw and let the kids decide who gets sent to unspeakable horror. Make it so the Skiff can attach and I can die happy.
3) Tatooine Homestead. It's just so iconic that it has to be made. I know you can't really create a "pit" for the house, but there are ways to make the top of the "house" and the "garage" work... I've designed it already (how to get it into Hasbro's sweaty palms?)
4) Jabba's Palace is a backdrop with some alcoves
5) The Cantina is done except for a backdrop and some tables and chairs
6) Palpatine's office. This one is a stretch... it hasn't been attempted in any way, but I did say wish list. Who doesn't want Kit Fisto's head on Palps desk? or a break away window to throw Mace out of?
7) Tantive Hallways. I don't need the whole ship, I just want a hallway. Capture the Leia with R2 moment, The escape pod, the entrance of Vader, the death of Capt. Antilles, and let your rebels and stormtroopers lie in the hallways after the battle.
8) Kashyyk platform. I want the wooden platform. They looked so cool at CIV at the diorama builders table.
9) I want a GOOD Carbon Freeze Chamber. The old one was a decent 80's attempt. Lets have a 2008 attempt, eh?
10) Theed Hangar. Again, we got a half-hearted attempt. Make it big enough for a Naboo starfighter and a doorway to the Generator so we can attack Darth Maul and cut him good (poor Qui Gon). Modular... think modular.
