On it's own, Judgement is a very good game. I've been on Epic Games's forums and the community is split on whether they like it or not. Some of them feel it's similar to Gear 1, which I personally found far more difficult than 2 or 3. The comparison to Gears 1 is good or bad, depending on your preference really.
Then there's the rest like myself who was a bit let down with it.
I loved Gears 3 so much, one of the best packages in gaming, Horde, Beast modes, fully fledged campaign along with some of the best DLC money could buy on the Xbox.
They got the balance in Gears 3 spot on, weapons, maps were all great and the gameplay was as smooth as ever.
They removed a lot of things in Judegement, which really confused me. Like only 4 modes on multiplayer and the disjointedness in the campaign.
This time round they've messed around with too many things, but I've played a fair bit on Judgement's multiplayer (especially Overrun) and it's growing on me. Gameplay is still exactly the same, but its very arcadey, when People Can Fly, the Co-developers of Bulletstorm came in to do this with Epic, then I pretty much expected it to be like it is.
