+The design of an achievement is open to the community. You can use an idea from other sets so long as the achievement badge and title differ. 
+
+When working on a set for a game that already has a set for another port, developers should put effort into differentiating the sets. While progression can often be similar between sets, one should use different challenges and different set structures whenever possible. For some games, the possibilities to differentiate sets are limited, and the design can end up fairly similar despite the developer's best efforts. Before releasing a set that is not clearly distinct from one of another port, consider requesting feedback from other developers or set designer, and if the design remains very similar, run the plan by DevCompliance for approval.

 ### In-Game Achievements
 
 Some games incorporate a set of in-game achievements that were released with the game. Any of these achievements can be used as long as they are not Unwelcome Concepts.

+### Claiming Multiple Ports of the Same Game
+
+Letting other developers work on other ports of a game is encouraged. For this reason, developers cannot hold claims for two ports of the same game at the same time. 
+
+Moreover, for the 6 months following the publication of their set for a game, developers shall ensure no other developers are interested before making a claim on a port of the same game. This is done as described below:
+
+  1. Contact DevCompliance and express your interest in claiming a second port.
+  2. DevCompliance will privately reach out to developers that have the game on their Want to Dev list on-site.
+  3. The other potentially interested developers will explain how likely they are to claim the game before the cooldown finishes. For example, if 4 months have passed, they will say how likely they are to claim in the remaining 2 months.
+
+Collaborations are exempt from this cooldown as long as the repeat developer does not do a majority of the work.
+
+For the sake of this rule, different ports of a game are releases on different platforms where the gameplay is largely replicated. Differences in presentation, theme or license is not enough to be considered different games. Content being cut in one port due to technical limitations such as lack of space doesn't make them different games either. When in doubt, contact DevCompliance before claiming.
