They have experimented a lot in Anno 2205 and they have done a great job on expanding the futuristic part of the series. Now we need a prehistoric Anno, which would be an interesting thing to see.
The paintball mode in this game is amazing. The game has some sort of horror charm to it to me, probably because of the old graphics. It could easily get a hunted vs hunter mod, if the community was still alive.
Blizzard took this title and butchered it until nothing remained. There is no soul put into this. All of the charm is gone. To top it off, veterans of Warcraft 3 can't ever play the classic anymore thanks to the publisher.
