I'd say activities like this would need in include the platform. From my experiences on Twitter it would just be too easy for others to hop on a popular name for marketing and confuse the heck out of people.
Unless of course the name context was given a namespace or something that could be used to indicate the source to consumers.

Subject: Should gaming activities include a host/platform?
Hey all,
(Expanding on http://wiki.activitystrea.ms/Gaming) I've been talking with a few colleagues about gaming activities and I'm wondering if others think gaming activities should include both the game and the platform or jus the game. For example:
* Anna Apple achieved Underboss in Mafia Wars
* Anna Apple achieved Underboss in Mafia Wars on MySpace
I've gotten mixed feedback from colleagues and I'd love to see if other folks have perspectives here.
Thanks-
--Rob
