Firaxis' Jon Shafer recently made a post over at the Quarter to Three forums
regarding the next patch for Civilization V
There are several things which we are looking at improving with Civ 5. Most of my time since getting back has been spent working on the interface, particularly with making more information accessible. These changes will go out with the next big update in a few weeks. The plan is also to make major revisions to the diplomacy system, and while I can't talk about the details yet, I think you all will find them an improvement. That will be added with an update later this year. Also included will be a number of AI upgrades.
Despite pricing issues here in Australia, AusGamers was thoroughly impressed
with Civilization V, coring it a 9.2/10.
