Mine:
Bad Company 2 - 8.5/10. Decent single player except for non-event ending with good variety and concise. Great multiplayer although could do with more unlocks (or better staggering of the ones on offer) and maybe a killstreak system (although following a COD MW style rather than MW2's ridiculousness) Changing player on the fly is good.
MW2 - 7/10. High production values for single player, even if story was pretty confused. Multiplayer is very addictive but lacks depth and too many bugs. Prestige system is still pointless - must be a better way of doing it to keep you playing. No incentive to swap guns other than a few more points.
Transformers War for Cybertron - 6/10. Enjoyable single player if you like Transformers, although would have liked more genuine characters not just generic classes of enemies to plow through. Multiplayer is enjoyable but for a third person shooter the arenas were all a bit too similar. The transforming mechanic works well though, but the weapons aren't exciting enough. Character models are good.
