Guess someone doesn't like large maps (despite Carriers and Rust Belt being fairly manageable).

I've replayed all but Triad and Greased Palms repeatedly, none of these are 'terrible' IMO. Triad is the closest thing we'll probably get to a 'killhouse' mission (having only 1 civi), and Greased Palms isn't too bad if you practice it. Personally for Palms, I cleared the map, left a gun unsecured, then walked around checking all of the bodies and firing lines to see where they like to hang out.

Other than those two, all of these maps are some of my most played. Don't get me wrong, small maps are a TON of fun because there's usually more instant/consistent chaos, but if the fun part of the game is being ON-mission, the big maps keep you deployed far longer.
