from what I read, neither seem that appealing to me
I agree. Except for the OP, the other posts are very thin & childish niaiseries.
I purchased it direct from Atari (because Amazon Canada has delayed its own release date), and I somewhat enjoy it.
I must admit that Mr Apple-and-Oranges was partially right (refering to another thread) : the visual quality is better than HM&M 5 -- but only in what concerns the landscape.
But ... one must consider that the HM&M 5 designers had to plan for the creation & random generation of map features on many scenarios & custom maps, whereas the KB designers had the advantage of concentrating on only one single map design. It's relatively easy, then, to spend time to fine-tune & refine the one & only map you are offering to players !
