Over all, only 1 game may use a growing subscription base, EVE Online, and even this can be a small growth over time. If the enemy doesn't see sneaking up on him from behind or his side, then he is able to not cry to alert his comrades nor will he use a chance to fireside his weapon. This will definitely be blockbuster FPS for multiplayer, self-assured in your fragging your buddies or complete strangers for hours.
