Settlers 2 - 10th aniversary edition is looking really great, I'm going to buy it when it hits the shelves.
I really, really, REALLY did not like Settlers 5 at all. It may be fun the first few plays and it indeed is a lot like Warcraft, but after those first few plays repetion sets in. There is just nothing to keep you going, its just the same over and over again
This is a flaw in all Settlers games actually, but the old ones were fun to look at with all the things happening on screen to keep you from getting bored, while S5 is just very plain looking like any other RTS which is not fun when a single game can take hours.
However I have yet to try S5 in multiplay, that would be a lot more fun I reckon.
