Can anybody recommend games that are similar to Rebuild 1&2, not exactly zombie games, but something where you are trying to build up a city and protect against an enemy (like zombies)
I think the reason why nobody answered you yet is because your question is both at the same time too specific and too large.
Too specific because Rebuild is quite an unique type of game. I don't recall seeing another game quite like it. Also why it is rated so high and why I consider those two games as part of the top 10 best games on AG.
Too large because... Well, defending against an enemy is what you do in like 90% of all games there is out there... Gotta be a whole lot more specific than that...
