This one made me laugh...
You want that from newest idea to oldest, alphabetical order, most developed to least, or how likely they are to get to the table based on compatibility percentages with each group?
Seriously, this is the Barking Alien blog kids. Anyone whose been around here before this post knows I'm usually working on at least half a dozen new campaign ideas at any given time. Most of these concepts never get beyond the initial 'hey, you know what would be cool' stage. A select few get nearly the attention of games I manage to run before they are shelved for one reason or another. Developing a Role Playing Game campaign is, for me, very much like pitching a motion picture in Hollywood, complete with concept art that's never used and going over budget on props.
All kidding aside, the games I plan to run next are...
I would really love to give the Orville another chance. I don't feel like my initial attempt truly captured the feel of the series and it certainly wasn't as challenging for the PCs as it could have been. Against my own better judgement, I tried to make it 'Star Trek Lite' instead of serious Space Adventure with more quirky characters. I missed the mark big time and want very much to make another go at it.
I would use Modiphius Entertainment's Star Trek Adventures system as I like it a lot and of course it designed (or at the very least adapted) to emulate just such a setting. I want to more fully flesh out the Orville universe elements and to do that I may have to wait until after Season 2 of the series has gotten underway.
Maybe my new campaign for 2019? We'll see.
A little secret side project I've been toying with for some time is a Wild West RPG based on the rules of classic Traveller. Right now it lives in a dusty corner of my computer under the title 'Pioneer'.
The idea first came to me about a year ago (maybe two) when I was trying to think of a system for running my very specific take on Westerns. I wanted something that had an air of realism about it but would still enable me to tell the kind of American Folklore, Wild West Ghost Story tales I used in my first and really only Western campaign up to this point.
The project is currently a bit unfocused. I know what I want for the most part but I am not sure how to present it or where I am going with it. Yet. It is very much a work in progress, though progress does continue.
Can I / Will I / Should I finish Pioneer in time to make it my next campaign? I haven't yet decided...
and getting honorable mention...
Sentai / Giant Robots
I have been powerfully inspired by Voltron, The Legendary Defender and haven't run a Giant Robot campaign in a very long time. I'd really love to do a game inspired by the Netflix animated series combined with more Sentai elements such as more individualized abilities and gear for the PCs and more Kaiju-of-the-Week enemies.
Maybe. I kind of like how they held off throwing a 'robeast' at the Voltron team episode after episode, making the appearances of said monstrosities extra-special.
Shelved in my mental archives for later.
Well, that's where I'm at.
Where are you?
