They can definitely be imbedded in - but I think it depends on who is working on the landscape area... I can see them being needed in the landscape section, but if we go with tiles for the actual city area, do you guys really think that the figures will be falling over all that much without them? I'm pretty much against the idea of glueing the figures down though, but I guess once on site whoever is there might need to make an executive decision.
Another option for the "tiled" areas is a tacky substance that can be put on the bottom of the feet of the figures, but doesn't stick like glue. It's used to hang posters all the time, and might work out fine.
One othere thing - how many figures do you guys think we want to have represented? I'm afraid of it being over-crowded...
Just as an estimate, here's a rough number of figure types I think it should have (take into account this is just a rough number) -
Stormtroopers - 50 or so - all the new VOTC/SAGA2 Sandtrooper style
Rebels - 15-20 - we do want them to be outnumbered I would think
Citizens - 75 or so - and to be honest, here's where we need to pick up on customs I think
