I still play all of the Saturn releases. Megamix has just tons of replay value. I never got into the later games as much as I loved VF2, but I still enjoy watching good players when I catch them streaming.
If you’re interested in seeing where the community is at for the latest VF (VF5:US), most of the discussion happens at virtuafighter.com/forums/ and there’s a regular kumite streamed by www.twitch.tv/akai_vf
