PC Gamer UK have posted up my review of Medieval II: Total War Kingdoms. I say things like this:
These four campaigns represent a gigantic amount of new material. It's all presented brilliantly - new animations and cinematics for each of them, and a unique front end and rack of options. This feels like four expansion packs rather than one muscular bundle. The smaller changes mean they all feel different to play, and the tiny tweaks and foibles mean it's not quite like Medieval II any more.
And we've linked this before, but it's worth reiterating that they got the inside scoop on Empire: Total War. Yes, it's got ships in.
