I rather enjoyed Extinction...one day and then not on another. It's because I'm not very consistant when I play RTS. Sometimes I'll be able to fly through them, other days I'm just totally useless.
The Ultimate Predator
I was always planning to, but I never got the time, and with all the reviews saying that it wasn't very good... I might ask for them for Christmas. or maybe one of them. Have you played Concrete Jungle?
I'm surprised with you been a Predator fan. Thought you would have got that. I hated AvP Extinction when it first came out. But I bought it this year and really liked it. I didn't give it a glowing review, but I found it better than I thought.
