The Fulda gap scenarion looks great, but
personally I would prefer a little larger area let's say 300x300km, that's 90000 km^2, still doable (less then map in LOMAC). It would enable to use WP forces too, for ex. Mig29vsF16A (with only Winders a lot of fun), Su25vsA10, Mi24vsAH64A). I believe that such sim would sell like a hot buns and eveyone would be satisfied (coop, online wars etc)
