Just for info, and to whet the appetite of anyone interested.
GMT have announced they're to do a Medieval CnC. Supossedly projected to go from 500 to 1500 AD. That's the good news.
The less good news is that it will be 2017 at earliest. The basic game will come with Byzantines, Persians and Arabs, which is good if your a fan of of the 500 to 650-ish AD era. But Lord knows how long it'll take them to get modules done for all the other eras.
Still good news though.
cheers,
Tom
