The last I was told, the game was about a balance between gameplay (Not fun) and Realism
The devs said once, they want to give players, more than exactly how WW2 was (How things worked, logistics involved etc), the 'feel' or ww2 in terms of the waves of troops, the balance of weapons and vehicles, how the battle flowed
Personally, I feel that philosophy has undergone some revision, which is a good thing for flexibility. I now think the mod should be about 'Immersion' since that covers realism and gameplay in its essence as well as a little pixie dust that cannot be defined.. But is 'good for business'
I still have reservations, not about what their philosophy is, but how they are getting there... Some wonderful architectures are still in their infancy, and some are going on a tangent, lotably, the communication apparatus and animation that I've always felt should go with it, sound (Which I declare should be closer to realism than fun, which is what it currently is).
But then I have more of an issue with the philosophy of development of the mod, granted FH2's quality is superb, I've always felt that the idea of a mod should be open-source with an open-communication between devs and players, mini-mods being given the devs' blessing, rather than a dissaproving frown or at best a tacit shrug. But most importantly, I wish the devs would be able to mobilize the fans to add on what they can, eg. Videos and movies and voice for various nations - AND making the game based in part on the hopes of the fans as opposed to a 100% 'how we want it'... but maybe that's just what I thought a mod was all about
