I've noticed that there are very few restrictions on linking Backgrounds and Factions. It's pretty open overall, and while that's not a bad thing, it does create some odd situations with some of the more 'concept-restrictive' choices.
For example, consider the following combinations:
Lost/Jovian (requires Second Skin trait)
Uplift/Jovian (requires Second Skin trait)
Uplift/Socialite (requires Second Skin trait)
Uplift/Ultimate (requires Second Skin trait)
While the need for Second Skin for many of these combinations shows a 'CP tax' assessed to cover the wierd factor, the first two do not require anything special to take. However, both of them certainly seem like really odd choices to me.
So, has anyone seen any of these odd duck choices crop up? Any tips on how it worked out?
