Alright I am not quite sure which forum this should be posted on but I noticed there is a page for Carcassonne for iOS and a page for the Windows Phone version. They both seem to be made by different developers but the iOS version has the Xbox Live achievements attached to it.
The Windows Phone achievements should be moved to the XBLA edition (making two tabs, like they do for most other windows phone games that also are on XBLA such as Plants Vs. Zombies). That way there is just one page for iOS, Windows Phone, and XBLA. Each version can be explained seperately in the one main page.
I created and filled out the iOS Carcassonne page, and I've played the XBLA version as well. They're fairly different games, using different online services, UI paradigms, methods of input and of course, being published on entirely different platforms at different times by unrelated developers. The modes are similar, but not the same, and the expansions vary by version.
