personally, i like zanzibar for most games. I hang out around the rockets on top early game and then later when things settle down after the original rush for the weapons i try to get my hands on a sniper rifle and take it either in the window of the cave since a lot of fights happen along the side where the other sniper rifle spawns or i get up on top of the sea wall which also provides a decent view of that side... however if u miss the other sniper then ur pretty much toast from up there due to lack of cover... also if i get the sword i like to hang around the base and use it to hide and stirke... works fairly well for me
I also like midship as well, especially neutral bomb and/or ctf classic. Not much to say about this one except the sword or the ppistol/Brifle own there shotgun is decent for defense as well
