Believe me... as a proud owner of DOS AH-64 Longbow and Flashpoint:Korea, I have pondered this question many times. I wondered if it was worth looking for a cheap copy of LB:Gold or LB Anthology, but the amount of time I spend playing it (since the latest DOSBOX works so well) is too small to matter. I can always get my 3dFX Longbow fix with Longbow 2.
I'll never forget the first time I saw a 3dfX Hellfire missile trail or salvo of FFAR's... Good times! Good times!!
