I love all of these maps because of the rebel opportunity, as well as the fun games all of them have to offer. Arcade is my personal favorite because of the rebel opportunities, as well as the fun and unique games it has to offer like tap terrorists, spelling bee, and csagario. All of the others have fun, unique games as well as opportunities for rebelling, which I love

Moonjail has great maps, but is also my favorite for sentimental reasons.
Least Favorite:
Obama
Dust 2
Dojo
I am a T main, and Dust 2 STILL is not fun. For one, the map has essentially no games, which if we EVER make it out of main cells, aren't fun at all. It is not fun to rebel EVERY round, allowing 4 Ts in vents and 2 up to scout just makes the map not fun to play. I have not even gone to some parts of the map as a T just due to the fact that we rebel too much. With some map changes however, this would be a map I could at least tolerate.
Obama, oh boy. For starters, it has no fun games except for hard climb, which I have grown tired of at this point. Secondly, it is made up of entirely untextured surfaces, which do NOT look good at all. Thirdly, none of it is fun at ALL, whether I am a CT or T, it is difficult to warden, especially because of all of the tight hallways and the fact that the Ts might have the bomb. It can be wardened though, but it is a challenge, and not a fun one at that.
Dojo shares some similarities with both Dust 2 and obama, like the WAY TOO EASY rebel opportunities, and the look is not my favorite, as quite a few maps share the minecraft map look. And the lack of games is also an issue, surf and climb are fun, but we rarely play those, and we mostly play maze/deathrun/deathcrate, all games I do not find fun at all.
