Mag update:
Just got finished playing a seven hour+ session (how do I manage playing the DualShock that long without any discomfort, SuperLink?), got to Level 18, nearly 19. It took me a couple hours to change from my COD style of gameplay. Wasn't just the different button-layout, it does have to be played differently. Then about three hours ago I realised that you could purchase weapon attachments and perks in the barracks menu. Got my self a new gun with some attachments and perks, been ripping it up since.
Have been Squad Leader once, and we won that game! I play on the S.V.E.R. team, who are the 'rebels/bandits' of the three outfits. I cannot seem to find out how to create another character to play for another outfit. Maybe you can't. Not too fussed, I like S.V.E.R. Valor company looks like roid-raging fags (sort of Gears-ish), and I can't remember what Raven company looks like.
Anyway, it's a really excellent time. If you're a COD player, it'll take you some time to adjust to MAG. Give yourself a chance to do that before you give up on it. The graphics are rubbish in some respects, but you've got to expect a visual-hit when 256 players are all in the same arena, simultaneously. Had loads of 256-player battles, now. All seems to run very smoothly. Haven't encountered any raging lag.
