Totally jumping on the 'I love this idea' bandwagon!
It'll be really interesting to see who develops what (if they develop anything at all) and how it's handled.
I guess my question is if there will be some kind of 'approved abilities' list and will characters be allowed to have an ability that another character has - and if yes will there be a number limit on the abilities, like only two people can have the ability to regenerate so that there aren't a million characters with the same ability?
