Superconductor CTF is the only CTF level I can really enjoy the gametype in (well, I like Rather Useless CTF v2 too, but I sort of made it so that would be unfair). A lot of people dislike it for the "quirky" part with the floatups and wind, but in my opinion this is exactly what makes the level fun. Even though it's relatively small there's a lot of different tactics you can employ and apart from offering great gameplay it also has awesome eyecandy. If there's one CTF level that I would nominate as "level of the decade" it's Superconductor CTF.

But I don't like CTF in general, so I go for Assault3, which while looking horrible (though Pyromanus' edit of it eliminates this point) and being fairly simplistic compared to later assault levels, can be really fun to play and brought my favourite gametype to JJ2. A great blend between Team Battle, CTF and Single Player, I'll always be sad that it is played so little

I've always hated bblair with a passion. There might be tactics and ingenious paths and whatnot in it, but somehow I remain oblivious to them and just see a below-average level that is way too open and full of random platforms and unbalanced pickup placement.

By the way, what exactly is a "levelset"?
