For the past few weeks I have found myself returning to my favourite multiplayer game of last year, Battlefield: Bad Company 2. It’s a punchy rascal of a game, but it also hints at plenty of things that could be better in the future, and reminds us of lots of things that have been better in the past. Things that might be better in Battlefield 3. Or 4. Anyway, what follows is a consideration of what Battlefield games have done right and wrong, and what Battlefield 3 needs to think about.
