This was one of my favorite games I think of all time it is starting to become what many of the other shooter games of the half life engine are though.
For me its like Mario 3 it was good at the time of creation but , now that new games like Overwatch are around i feel there will be a decrease in new players so unless you want to start this game with a friend I don't see it getting any better than it is now
I love this game and I hope new players joining love it too and in the words of Gaben "Thanks and have fun"
