We have something called de_lego the bad thing about it it's that there is no kit so if i always plan the bomb and they get to defuse it late then i will always wins. Putting de_train, de_inferno it's not a bad idea however the space of the map is so huge
that it will take long time to kill the enemy. Adding maps such as the de version of lego is really a good idea but those maps are somewhat identical in every area of the map. If CTs can get to the bombsite before the Ts then it's a good map.
