homeworld 2 offers such epic battles. - when a fortress guarded by a few battleships and dozens of frigates, gunships and several fighter squadrons are attacked by 2 other players with their fully equipped motherships + battlefleet,... it looks very much like that
you can hardly make a difference between the enemy fighters and your own ones - you rely on the AI, the enemy bombers approach covered by the fighter swarms while the big battleship gauss rifles cover the large distanceses across the battlefield. - swarm pod missiles and ion beams cut through the screen while juggernauts deliver nuklear warheads to the enemy capital ships.
( well, not the original hw 2 - but i play the point defense mod sometimes )
