I really like it when games purposefully play with your sense of morality, Spec Ops is a good example JamesC. I never played World at War though, I'm not sure how it was executed there. I'm working on a little indie platformer at the moment which will have it's own moral conundrum near the end, assuming I don't bottle it!
On topic, I played a bunch of Rogue Trooper Redux with a mate, it was great stuff. It takes a little bit to get going but once you're all powered up with your biochips and the real gameplay has shown itself, it's still as good as I remember.
We also booted up the PS2 version afterwards to compare, it's interesting. Theres something more cohesive about the art style of the original, its much more stylised and then in the Redux they've injected some realism, perhaps creating a clash. Redux still looks cool though, the extra resolution goes a long way for a kick off! Does anyone know if it does 4k on the Pro and the X? that would be cool.
