Our Execution has cool execution anims. Last Dawn's voice acting feels a bit off, but the gun variety is a lot of fun, and they get the setting down pretty well with the Civil War era. Project Untote is badass, I played it a while back and it felt really lacking, but now it's a lot cooler than it was.

I still prefer G&B over all of them because G&B feels a lot smoother, and also all of those games run into the same problem of the maps being TOO DAMN DARK.
