Oops, sorry FlyXwire, have only just got into SDOE-WW1. Having given up after a failed dual install, working fine now. SDOE has many fine aspects (including the clever "comressed theatre" approach we may have to live with for WoW) but has always lacked a decent campaign. If a set of WW1 missions could be presented in the SDOE's existing campaign interface, rather than a set of missions attached to a plane, that might be better. Anyway having recently got it working, I'm getting back into it.
ArgonV, that new Somme terrain indeed looks much better, so THAT was what those Ilya Mourometz were flying over.
