I played CTF a quite a few times in Rise of Flight and it can be fun. A bit different than what you described. You have four, five flags per map, you have to CAP them at close range for some time in order to capture. You have a timer showing your progress. If enemy planes show up in the "CAP range" the timer stops until you shoot them down or they go away. once you capture the flag, the base attatched to it becomes yours and you can spawn planes from there to deffend it, or attack the next flag.
It can be good easy fun to have with a bunch of friends and a bunch of beers.
