forb, its pretty massive, big enough for FFA, although i agree that i also would make a cool left v right map... possibly for gundam because i know that big maps are optimal for that game
i think any big map with mirroring, such as throne and DSI can be just as good for FFA as for team games (thinking back to "old style" RTS maps for starcraft etc... a lot of them were balanced for teamplay as well as FFA)
for the map itself, it looks incredible and a lot of fun to play (although why would we expect any less from you beherith, you've set the bar high

)
from a distance (1st pic) it looks a bit like someone used a piece of tinfoil to heat and crumble some hashish
i love what you're doing with the specular textures and bumpmaps and suchforth; i dont think im going to make any maps until next version so that i can employ these new methods...
tl:dr one of the sexiest spring maps yet
