Hmmm, looks pretty good, they'll need some serious net code to minimise lag for 250 players. I'm down to 10FPS with just 64 players.

Well, 256 Players sounds good, but to be honest:
Most players are to dumb to use the teamplay tools of BF2 and BF 2142 (Squads, VoIP, Comroses). MAG would suffer from the same problems if Sony don't enforce the use of the tools.

The Vid shows what Zipper Interactive has learned from DICEs BF Games, like the Bonuspoints for the squadleader.
It also shows what some weak points of BF have been avoided, like the por immersion in the gameworld (landed Helos as Spawnpoints !) or the IMBA Airforce (seems that in MAG no player can fly, and airstrikes are scrippted like the BF2 Artillerie).

Also interesting would be the way Sony wants to distribute it.
Did you must pay each month a fee to play ?
IMHO the best way to fund a Server capable to host 256 Players.

CYNIC, n. A blackguard whose faulty vision sees things as they are, not as they ought to be. Hence the custom among the Scythians of plucking out a cynic’s eyes to improve his vision

It is just part of the mighty PC code which all things PC must abide by, as in 16, 32 & 64 player. 16, 32 & 64 bit. 256 colours. 64 x 64, 128 x 128, 256 x 256, 512 x 512 & 1024 x 1024 texture maps.

I tell ya its a conspiracy just like the DaVinci Code.
