Loved the mod hate that there isn't a BF2 version.
There's a long story behind the lack of BF2 version... basically not enough 'producers' (modelers, skinners, coders mainly) were active in the team and while lots of plans and ideas were thrown around the mod never really reached completion. We also had trouble getting playermodels working etc etc. A classic tale of stagnation in a mod, really.
If it's any consolation, it probably would have played a lot like FH2 does, so next time you're using an SMLE, try and imagine the Jerry you're shooting at has a Pickelhaube on...
I would love to collaborate in BF1918: 2
You're a talented modeller, if anyone can get actual work done on this it's you. If someone really wanted to get a version of BF1918/2 working, IMO the best way forward would be to make it a minimod of FH2. A number of weapons are already there (SMLE, Webley [may be wrong version], Luger, Lewis, Pattern 14/M1917, Colt 1911, Vickers), as is the BF1942 comms setup (BF1918/1 has voice commands that require that setup). Not to mention the good-for-rifles gameplay of FH2.
If permission could be secured from the FH devs to make a minimod on top of FH2, and the co-operation of Inside1918's community could be obtained, this could actually happen - the hardest thing to do would be getting German and British WWI playermodels into the game and working properly. The best goal to work towards would be a simple trenches-based map with two sides wielding rifles and NCO kits with pistols, and machine gun emplacements.
But obviously, even this 'simple' task would require a lot of work. I can lend a hand as an administrator keeping tabs on what needs to be done in the project as a whole, but my lack of skills and time to learn said skills means I can't really do much more.
