Everyone voting for the last option on the current poll is already missing out. LOAF's compiled a list of Wing Commander games on platforms other than the PC. Some are direct ports from their PC counterpart, others have some neat things added. Take the 3DO Wing Commander 1:
3DO: This is 'Super Wing Commander'. All of the graphics are redone in Privateer-level VGA. It has some new 'bridge' plot points (characters occasionally mention stealth fighters) and a 'middle' set of addon (Secret Missions 1.5!) missions about blowing up the Sivar's base. Full speech, ships look different, people look different, etc. Amazingly, of all the ports this one *plays* most similar to the original game.A comprehensive list is online in the Article section.
