I've brought up this topic before in the old forums which I think needs revisiting since nothing about it has happened. Wouldn't it be to have better accessory sets to go with the figures?
Here's a few that comes to mind:
1) Rebel Hangar - how about those lights, tools, etc
2) Cantina - chairs, tables w/lights, mugs, etc
3) Jabba's Palace - similar to Cantina
4) Bags of weapons like Stormtrooper blasters (the rifles with the CTC Stormies suck!)
