I'd definately like to see a multi-weapon FFA map with this sort of design.
I'm not really much of a tourney player myself. The map resulted from an experiment that got carried away. :-)
I agree with Kell about the pink skulls. Actually, the colour comes from the zapscroll shader. When I built the map I still had my old monitor and a Voodoo 3 3000 card so the colours looked OK. With my new set up Q3 maps started looking pinkish. Pity, 'cos it looked better on the old system.
Personally I didn't think a level this small was likely to have much longevity anyway.
A note on quad in "Rail Arena" maps: If the mapper hasn't 'banned' the machinegun, whip it out once you get the quad! Not as much aim required and you get more bang for your buck :-)
P.S. 8 from me, though its a 9 for a rail arena.
