I recently bought a fantastic boardgame that can be adapted to Traveller (esp LBB). The game is about running ship to ship space battles with boarding actions. Each ship has a deckplan built out of modular sections for helm, missile bay, cargo bay etc, with a perhaps 2m grid. Your character move around on the ships when doing boarding actions but also during regular space combat. Run to the helm to line up the ship for a broad side, rush down to the engine room to repair battle damage etc etc. The shipboard action is very well integrated with the space battles; enemy fires at your ship and some modules may become damaged including those inside them. Every crewmember (Pilot, Combat, Engineer and Science) has something to do at all time. Tasks are performed rolling 2D6 +Skill (very LBB ish). The game is played with a referee with character advancement adventures etc but there are no character interaction rules, encounter tables etc. I've played Traveller since the LBB and I haven't had as fun since Snapshot, way back.
