I was watching this youtube video today and i was totally in RAGE! because source engine was 1st place and UE3 on 2nd place!
Tell us what engine do you like more and why do you think that. And please don't be a 12 yo kid, behave like a normal person.
I personally like UE3 because it's MUCH better than source engine, not only because of graphics but because of physics, map size and it's friendly community and because it's FREE.
