I have in mind a couple of no-Mech scenarios. First off would be a scenario set against the Capellan-Supremacy War, a conflict in BattleTech "pre-history" (before the invention of the battlemech). The second one would be a battle based upon the old TSR minigame Revolt on Antares. The troop types in Revolt (laser tank, hover craft, jump troops, power armor) match up wll with BattleTech coneventional forces. To do that one I'd need a more recent rulset, since my BattleTech Manual does not contain any power armor rules.
In my Starmada posts I already mentioned my Aeromada project, converting the original Aerotech over to Starmada rules to do some dogfighting.
As with most every other BT fan out there, I want to webpublish some mech designs. Unlike most BT fans, all my designs are meant to be historical derivatives of existing mechs. For example, I want to stat out the prototype Blackjack that moved 5/8/0 and had flamers instead of ACs.
