I'm looking at running a game surrounding a sort of fringe Rogue Squadron, not unlike Wraith Squadron. Players would have their own custom starfighters, rather than all being assigned a standard model.
I had an idea that I could make 3 or so varied, but balanced stat blocks, and let them create their own shape and design around a stat block, and then get to do some after market upgrades. The basic models would probably follow the basic starfighter stereotypes: agile and fast but not heavy hitting (A-wing), slow but tough and packing a huge punch (Y-wing), and something intermediate (X-wing).
Does anyone have any methods for making comparable but balanced fighter designs? If not, would anyone be up for helping me make a trio of diverse but balanced ships?
