This is a moderator approved thread for the posting of any ideas and suggestions that are not worth their own thread (as the name would suggest). If you have a relatively small idea, or a collection of relatively small ideas, it would be beneficial for the sake of forum organisation to post it here. They'll probably get more attention here than they otherwise would, and the forum will be much more easy to browse.
"I would like this new button", "It would be cool if this particular unit did slightly more damage" and "Why not include this wonder in the game?" might be good examples of ideas that would perhaps be best posted here.
So, what are some cool ideas or suggestions you have for the next instalment of Civ, whether it be an expansion pack or a new game?
