Edit: Ok, so I finally played it. Looks stunning, Q3 pushed to the max, but I just don't like the alien vs human thing. I didn't like natural selection, I don't like Tremulous. But it's cool that there is a first standalone Q3 mod + it looks so awesome. Now I'm waiting for WQ3 standalone to get some people on the servers.
