I mix it up A bit, anything that will accept large diorama basing for ease of movement for big armies. Impetus i gave to say is my favourite the ability for units, a command or whole armies to move across a table rapidly has lots of pluses particularly for cavalry or irregulars like the Gauls, well drilled troops stand as expected, but I also can play Hail Caesar or WAB even, I have purchased To the Strongest and ALDG but not played a games yet.
We have unique offerings to our customers, the ability to walk the battlefields then Wargame the battle so it adds a extra to our games, plus being able to bring your partner for a holiday in a rare noblemans L'Hotel Particular (basically a chateau in town with a large garden) in a historic city.
The goal is as long as Gauls or Romans are dying in droves and we both have fun nattering away, with beautifully painted figures on a outstanding table that is the ideal!
Cheers
