If I'm not mistaken, the guy that made FH so special (with its pretty realistic physics, non-wobbling tank, tank combats, heavy surface controls of the aeroplanes, etc) is Takiwa... then he moved to the Frontline mod, which fate for BF42 is unknown, but then it merged with BG42 to become BG:F.
FH was so over the top back then. It quickly introduced me to more WW2 vehicles than any other books in the planet that you can read in less than a week without getting bored. From the guys back in FF like Jummy, Bunny, Meadow (where is he now?), Yosssarian and many other guy I learned politics. From Lightning, Mudra, Anlushac, and most FH fans I learned history. People here still look down on gamers, but they know nothing about history, one of many school subject that we must take back then. So, I found FH a bit educational and contradict many other reality-bending games like Command&Conquer, MoH:AA, or many other title many people deemed "quite realistic."
I chose this community over many others, because it has this unique mix: gamer, into realism/accuracy, internet-savvy, WW2 and military enthusiasts, generally not afraid to push on difficult topics (it was much heavier discussions back in FF).
I moved on from other communities of my hobby like Avsim.com, and several other add-on developer forums from time to time. Even though they shared the same interests with me, but the people there aren't that up to my taste, too many typical CoD noob-like joining, untouchable devs, shallow discussion (too many stupid arguments on typical Airbus vs. Boeings), it gets tired easily, so I chose to move on to real life, hanging around with aviation enthusiasts community in real life. But for FH, it has been like 6 years (since late 2005) and still going on.
