The cause of everyone's problems with CIV 5 is essentially the two things everyone thought was pretty cool when first heard. 1. Hex 2. No Stacks. Those two excellent choices basically threw away 4 versions and 20 years of development. All the previous versions were essentially similar games with engines and AI that just kept improving upon other versions. Now, i haven't bought it yet, I am waiting for patches and praying for removal of STEAM requirements, however I am willing to accept there are going to be some issues because they have had to write a completely new game. I'm looking forward to learning a new game that will hopefully (eventually) cause the same addiction as previous versions. So, I accept, I thought the changes were cool and thus I must be patient for the game to develop a little more. Cheerio Edit: I am referring here to a rather large change to the software causing all the problems as it is a brand spanking new development.
