Ok, we only got a handful of votes, but I think we can go from here. This will be the initial schedule.
Frostgrave - will run through June 2017
X-Wing: Heroes of the Aturi Cluster - July thru Dec
Legends of the Old West - January thru June 2018
Test of Honor - July thru Dec 2018
X-Wing requires minimal prep work, so it makes sense for it to start next. LotOW will require you to get some cowboy minis and get them painted. We'll also need to build up some terrain.
The main idea behind putting this on a schedule is you have the 6 months to get the next game ready (minis, terrain, etc), then while playing that system you work on the next one for 6 months (minis, terrain, etc). So for the 6 months we'll be playing X-Wing you should be building up your Legends stuff. Come January we'll jump right into Legends, then you can start working on your samurai.
As I mentioned, I have the rules for Legends. I'll post them on my Dropbox and put the links here. There were 4 books released for the game, but one (The Alamo) was more focused on mass battles. We'll stick with the main rulebook and the Frontier expansion (in case you want to play 7th Cavalry or Indians.) I also have the 4th book (Showdown), but not in PDF format yet.
Basically you get $200 to buy heroes, henchmen, and their equipment. That will get you about 7-10 guys, depending on what you buy. You can start with a hired gun or even a Legend like Wyatt Earp (though that will significantly reduce what else you can buy). Hired guns and Legends cost a retainer between games, if you can't afford it they leave your party and you need to buy them back at full price later. It's risky early in the campaign, before you can build up a bankroll.
We'll play some one-off games between now the January, so everyone can get familiar with the rules. I'll have some loaner posses for these if needed.
For me, I plan on running a lawman-themed list, based on the Lincoln County Regulators, with William Bonney (as a regular guy, before he became the Legend Billy the Kid). At some point I'll buy the Legend version. Just need to keep William alive!
