Aaaah... but if you know you're not going to be able to use Novian Shop resources for a silo or guild hall, and you don't intend to build a compatible shop, you might be more inclined to simply destroy the leftover unused ones instead of storing them, lessening the propensity for having Novian alts. Maybe.
You also might be less inclined to go after a plot in auction if you know the "effective Novian value" vs. the cash investment isn't gonna be that great a return, thus distilling the competition down more toward those who would use it as-is or for similar structures... which might also help the community retain some key public structures. It's all a hedged bet at this point, but it's an idea.
*nod* indeed... if I put in the time, I'd like to retain the fruits of that labor - but at the same time, how complex a system do we ask the devs to implement (and when does it become not worth the manpower to design and code)? And how hard would it be for new (or even veteran) players to understand? Gotta find a middle ground somehow.
