Age of Strategy Forums

It would be more realistic if players could conquer and occupy big enemy structures like castles.
It could work just like for the town centers: Kill all occupants, enter, it's yours. It wold force the owner to defend his castle lest the enemy uses it against him...

this is the basic principle of the game - you need to destroy everything else - maybe we can talk about a unit that can "convert" a building - but this is a different idea.

Or perhaps a special fortification that acts like a town center but has its own stats sheet and attack. Would this sorta thing be possible?

I understand the basic idea of the game, which is well-known since "Warcraft" (the original, not "World of..."!) and the "Age of XYZ" series.
The (my) idea is of creating a strategic structure which remains unless willingly destroyed, and would be fought over. Something which has a high strategic value, and can be taken by the opponent, which would give him an immediate advantage, one he wouldn't have if he just destroys it and has to build (buy) another one in its place.
Building strong points would become as much a security as a risk, for the enemy might capture them and fence you in.
