HIGH TTK, I don't want to play a sequel to Titanfall. Low TTK ruins FPS.
Campaign mode like StarCraft II with Jim R. MC with his own ship being able to explore planets with main objectives and side objectives.
Multiplayer where Clan/Guilds can square off on an epic level. Several planets/maps simultaneously, each planet is a hardpoint, each Faction possesses a carrier and each Faction must capture all 3 planets to be able to assault the opposing carrier (space battles). This would be a beautiful blend of RPG, FPS and RTS.
