Look's like Mech Warrior a bit - anyone remeber that?
I tend to agree with Phatbambi on this one. BF2 is excellent because is simulates a battle that could take place now with weapons of today, so there is an element of realism when playing.
Sci-fi games rely too much on conjecture of what the future will be like. However in saying that this leads to a lot of creativity yes, with made up weapons, vehicles etc.
I will certainly buy it but even if it was released today, I doubt if it would take my interest away from BF2
