i'm new to UT99 communities play pub servers (the pug server level of play is too high from what i see in casts, etc. 15y too late ^_^ ).
That said, i would probably play a SaCTF. Even with my crap aim i would enjoy it surely. I admit it's not that much different from iCTF given the aim many players have but pwr-ups would level it a bit or at the very least make for more interesting flag runs.
No tele, hard work/skills to fight to and back to flag is more interesting than tele a map in 3 sec to the flag and then fight, but hammer might be nice to have some sort of boost to add unpredictability to the moves.
As to pwr-ups i would leave them regular pwr-ups no tweaking and have them all (even invisi), it's head hunting not shock.
Can't/won't try sDom season because i don't know maps and its too late for that, although in time i will join on mirc one of this days/weekends (especially if saCTF/saTDM comes to life even if server only).
Maps, there are plenty of regular/popular CTF maps that could be played in saCTF imo, they would just need a different approach, more nw tactics then iGIB tactics, maybe a few tweaks to have more armor/pads/belt/etc..
Think that answers all the questions made on top of thread, just a n00b opinion i'm sure, just my $0.50 o//*
