Question to the modding gurus out there:
Can y'all think of any way to tie a city to a unit, so that the city can build improvements for the unit. I'm thinking of making the Golem more fun (and potentially actually useful). Perhaps restrict one golem per city, and then you could "build" the golem a +5 fire attack, etc.
A less-awesome way to do it would be to add buildings that give (e.g.) +5 fire attack to all subsequent golems built. But the first way is so much more thematic.
Perhaps a similar idea (mentioned somewhere else on here, I think) would be to tie a summon to a hero, so the hero could then cast more spells to further buff a summon. I'm sure you could come up with all sorts of things: -5 hp on hero to +10 hp on summon, etc. etc.
As long as we're fantasizing, hell, have a spell/building that requires you to sacrifice an item and then it gets added to the golem/summon, etc. etc.
Maybe this is all v1.1, 1.2, or expansion stuff, though.
