Well, I have an idea that I've been thinking of for a while now, but I can't run it until I've finished with at least one of the RPs I'm doing now.
At it's heart, I'd be running a 40k RP based on my Covert Operation rules. RP's tend to get the most activity nowadays, so that seems like a good bet. Ideally, it'd be nice if someone else could run a similar 40k RP at the same time (possibly in the same part of the galaxy, so they can be affect or reference each other in some way. A unified campaign setting for the forum). Then, to expand it to the entire forum...
Battle reports: anyone playing a game can post a battle report as part of the setting. Vassal games are greatly encouraged, since it doesn't require you to spend money. Previous edition games should be allowed to let ex players still take part without having to learn the newer rules.
Fluff and Stories: Spek for itself. Write something for the setting! people would be encouraged to include other people's characters. Incidentally, I would like to request that the setting take place in whatever part of the galaxy BigToof's character's are. I want Lorilune and the rest to be part of this, if possible.
Hobby: When I run my RP, I have every intention of converting models for the player characters and possibly any major villians. Diorama's would be great fun too. Pledge your army to the setting by doing an Army Showcase.
House Rules: My planned RP is already based on them. Also, house ruled characters,
armies, worlds. Custom scenarios could be fun too.
This wouldn't be a contest (although contests could be run as part of this) as contests require rules to be fair and those rules could restrict what people do. I was thinking this could be more open ended.
Maybe this should be split into it's own thread in the comments and suggestions board?
