I think one of the reasons I hated the closed was that I was playing the closed of BC2 at the same time and it just didn’t compare. However, once I put some time into the open beta of MAG and unlocked domination (the 256 player mode is locked initially, unlocked at level 10) and started to follow the flow of the game and the maps it really grabbed me. It’s much more unforgiving than battlefield, there’s little opportunity to make a big difference as one player.
Battlefield felt much more immediate, and a lot of the things it does better than MAG (particularly medics/engineers) but it certainly has that “something” that makes me want to keep playing it. The FRAGO system (whereby leaders can indicate the target points to capture which players will get bonus xp for) worked really well, and in my opinion (when used intelligently), enabled easy changes in overall tactics to push different areas of the map etc. The lack of airbourne/ground vehicles also gives it a different focus as well.
Personally I think they work well side by side, and I’ll certainly be purchased both MAG and BC2 – As well as continuing to play BF2/1943
