Arabs vs Templars (any Crusade battle)
Vikings (THE REAL Hardrada, not the cRPG imbecilic version) vs Britmy old friends (Stamford Bridge)
Teutonic Knights (Livonian Order) vs Russian Drunkards (Battle of the Ice on frozen lake Peipus, map made by Vagabond on my request)
Turklings vs Serbs (+ some minor bosnians and albanians, Kosovo Polje, starding odds: 3:1 in favor of Turklings, not only for historical accuracy but for fun as well since they will probably teamkill 1/3 of their army with initial charge & swinging, we gotta keep it interesting)
Seljuqs vs Byzantines (for odds see the comment above)
Scots vs Britmy old friends (Falkirk, Bannockburn, even better if someone could be bothered to add that Scottish equipment in this mod)
Normans-French vs Britmy old friends (Hastings)
etc, etc, plus:
Big Clan Battles = big + little clans vs other big + little clans, organized like it used to be. Or even better: since Strat is mainly about 2 blocks you don't randomize the clans but instead just have big organized battles between members of those blocks with some clear rules to prevent nonsense. UIF and their asskissers on one side vs Resistance & other weaklings on the other side.
I can see at least half a dozen interesting Sunday evenings throughout 2014, maybe even more if someone adds more ideas for grand battles.
