Here is hoping matt means WW1, but I know he really likes age of sail. I've also had a thought, that the Mongoose "getting lots of posh printing stuff" may well bestow the ability to publish not just craploads of roleplay supplements but also to publish and expand wargaming lines not tied to mongoose produced lead (ie not restricted by model release schedules). I know anything released for acta is dependent on the availability of minis but this is not true of VaS style games, or indeed any game that uses a Mongoose game engine but relies on pre-existing figure manufacturers ie historical gaming.
