Ok I had a brain storm

Take [URL=http://www.youtube.com/watch?v=kRQt4TONJMg]Shadow squadron[/URL] and build it up from there, you have 6 ships to chose from( 3 power based,3 speed based) with customization on all stats(speed,power shield,armor,repair,weapon power,weapon type) and starting weapons ,ect. Add you have 3 weaopn types loaded to a ship each has an over dive/charge function, there are 5 weaopn categories Missile class, Heavy gun class, Repeater class, tracking gun class(which offers auto turrets or tracking shots).(if you don't recall this is more a shooter than sim and have a set amount of power to make it through the whole game with few and far between energy rechargers)

Add in drops for 12 different weapon you can pickup and drop freely then offer multi modes of play. there are 3 main types of play modes and many sub categories. Main play modes are Fumes where you get no power drops and only a few one use fueling points between areas.Energizer where you get energy drops randomly.And unlimited where only jumping and weaopn(at a half rate) use power.

The single player and same console co op sub modes are
Free for all where you tackle zones anyway you want,the edges of zones would be jump points to move to a new zone.

Adventure plays to the story.

For co op you have the option of using 2 small ships with split stats or 1 large one, one person flys the other shoots.

Online sub modes are
Free for all and Adventure which can offer death matches with or without enemies, team death match with or without enemies.
