It reminds me of the vi series
and i like the simple no-nonsense look on concmaps. (unlike another map of yours i've played today: ff_zion or something, confusing with the ledges)
anyway, i've installed FF for the first time since like 10 days after the 1.0 release, and i think i'll stick with this. time to say goodbye to TFC. i hope to master FF concing pretty soon
