Still Caesar4 - I think this game is going to eat me alive, just like C3 did. There's a few things that I don't like compared to c3 - it's somewhat easier, for one thing, and combat w/your legions is more pointless than ever - but overall it has the same city-building addictiveness. Far better than CotN in that regard, say. The editor is buggy, difficult, and almost useless, tho, which is too bad.
There's a huge, "pure" pre-order-only sandbox level that was immediately uploaded by fans so everyone can have it, haha, and it's a peach of a sandbox, no doubt.
