Instabuy!!!
While this game certainly has its flaws (p.e. "recruiters" from workplaces tend to NOTORIOUSLY turn back just before reaching housings), it's really enjoyable. And addictive.
Thanks GOG.
bansama: What's the combat like in this? Personally, I'm interested in the city building aspect, but combat in these games usually annoys me.
Very simple; the attacking army comes, you send your cohorts there to battle them, and then you watch and hope your men get the upper hand. In short, it clearly isn't the game's strongest feature.
(Hint: if you manage to thrill Mars, he'll smite down most (or even all!) of the next army that dares to invade your city.)
However, after the first two tutorial lessons, before every level of the campaign, you may choose between more peaceful and a more military-oriented scenario. In the first I-don't-remember-how-many levels, there's absolutely no combat in the peaceful ones.
shitpants: If [...] some day I would like to get some extra room for my empire, is it possible to "borrow" it from neightbours (with bunch or pretorians, of course :) ?
No, you're always restricted to the map you see before you. You can only use your soldiers for defense (and for helping Caesar when he asks for it).
TheCheese33: Can you get murdered if you do a bad job?
No, but you can end up as a slave on a galley ;-).
