I prefer battles along the lines of BraveHeart or something in the medieval or ancient civ (roman,greek,etc) vein, more one on one and up close and personal.
VR likes to see the fear in his foes eyes before he keels...this explains why there always seems to be a VR horde of thrall chasing. Seriously, I totally agree the less "modern" ways of doing game battle are more fun in general. Besides, if more mass destruction is in order, we always have Rocket Dorf Fest.
We've gotten as recent as the Wild West but I don't know if OoH has ever even "officially" played any WWII games.
A long long time ago (in a galax...oh forget it) Baak NKI and I played a few games of WWII, not sure if Baak made then official (see giant red stamp coming down on official requistite), it might have been before we bacame an official order??? Even some coop games with the plugin (wall of murithene where the trow are replaced by tanks). The graphics were very cool, but it was quite as fun as regular myth if I recall.
We also played some Alien Tide, which was crazy. Alot of very destructive units in that plugin. Worlds Collide got some good play too and once was in the H'Pak map rotation.
