alright, here goes....
i like hidden valley, but for me, because i dont snipe well at all, its a little big and runs long round per round. On the plus, nice placement of buildings and such. Maybe crates and such in the middle should be bigger for better cover running and gunning and such.
On simple city, perhaps some of the bulidings burnt out( jagged walls and no roofs)with better acces to targets on second floor locations and vice versa, better targeting from certain buildings with 360 access to the outside. Always alot of hunting in the end.
Overall, fAntastic job boomer. I cant imagine trying to make a map...the best I could do was a 4 hole golfcourse on SIMS golf free download, and i would never play the course i made in real life....DOH!!!!!!!
