uh dude if bubbles weren't a thing maybe all of every non-hosted mission and campaign ever posted about would not be smaller than blue planet??? just a thought~~~
Here's a thought~~~~~~~~~~~~~~~~~~~~~~~
BP is the most popular and inspires the most discussion because of its own merits. It takes the Freespace universe that people are heavily invested in, and adds a complex, compelling, well written story with multiple layers, that gives as much answers as it raises questions. This sparks discussion and speculation amongst the players, which creates forum activity.
In addition to the story, it also takes the freespace gameplay and makes it make sense in a consistent inuniverse way, and expands a lot of the military feeling in a natural and logical way.
It's ****ing catnip for Freespace players.
The simple truth is that no other project has accomplished the same things BP has in this regard.
Diaspora: Captures the BSG feel perfectly, but the campaign is a self-contained short story that doesn't inspire any debate. It is exactly what it is, what is there to talk about outside of telling the devs how neat the models, music and BSG atmosphere is?
JAD: Funny, witty, incredible polished and technically accomplished. Comedy and lightheartedness makes people laugh and smile, but it often doesn't invoke questions and serious forum discussions. And there are probably also a lot of player that will scoff at the notion of playing a campaign that isn't full of grim and dark and deep war despair. Gotta have big blocky grey capitalships in a post-capella setting or
no go.OldWoD: Another case of a self-contained story with few open ends to talk about. Aliens show up, you kill the flagship and win the war against aliens. Hurrah.
NuWoD: With the first episode release, the story hasn't really taken off yet, Dawn hangs around with Justice and Tempest and does mercenary things. There isn't too much to talk about here yet. I'm not that suprised there aren't 50 pages of discussion there. Of course it also has that 'oh so very icky anime influence' that seems to disgust the grimdark crowd so much. ¯\_(ツ)_/¯
What you preceive as a 'bubble' is really just that easily explained. Posting in one forum doesn't prevent you from posting in another. There is not some kind of tribal war going on where you pick a side and then only ever be involved with that. Some campaigns and stories just invite more activity than others.
