I've been considering another Twilight 2000 or ALIEN game, but the wife isn't interested in either.
I've been considering a MYZ game but hadn't actually acquired my own copy... but the Humble Bundle cured that. ($43 for all 4 cores: M:YZ, M:E, M:GLA, and M:M) plus a bunch of sectors, and two campaign books... I went overbudget this month... but... the wife is interested in MYZ, vaguely. I might be able to get a bit of loopy mutant action in.
For 4 of the last 5 years, I never had to consider her tastes, because we weren't RP gaming together... but she's back in my Wed. group, and I do need to keep her tastes in mind. Which rules out a BUNCH of games. Including Alien and T2K 4E. She's not thrilled about Blade Runner coming up, either.
Justifiers has the hangups of it being a largely serious anthro setting, and people not being able to play anthro games without assuming it's supposed to be a Looney Toons special knockoff... instead of the moderately hard (harder than Traveller, but not much) Sci-Fi setting with Anthros. It also has the issue that the PC's start out as indentures for the lab expenses in their creation.... The anthro willing players I've got won't touch it because of the slavery issue. The players who wouldn't mind the "working ourselves out of bondage" angle won't touch it because it's an anthros game.
Albedo has similar issues with Justifiers. But it's also got the hardest SF ships of any RPG I own Fusion Torches, combats are single pass, and preprogrammed before engagement, PC's just have to ride it out as their programs get executed by the ship's AI during the pass, and the best weapons are KKMs...
I've long considered a Batlleforce 1E + Mechwarrior 2E campaign. The players I had who wanted me to run Mechwarrior hated Battleforce. The players I had who liked Battleforce hated Mechwarrior 2E. (Battleforce 1E is a much faster, simpler, and somewhat more abstract combat system than Battletech itself.)
Jovian Chronicles... Get to the point about mechs, and the hard SF fans say "No Way!" Get to the "Hard SF with Spin Grav and newtonian movemet" and the Mecha Players tend to bolt. I've got this idea for a CEGA assault on one of the cylinders in the trojan asteroids. Was thinking of PC's as residents thereof. (Inspired, of course, by the Gundam novels.) WHich, being on the defensive chases the last of the willing players right out the door.
I've considered a Mekton Empire game for YEARS.... Wife isn't even vaguely interested, and I have lost my love of Interlock as a system.
I'd love to run the setting/scenario from The Mechanoid Invasion, but I'm way too lazy to convert it to a decent system. It's such a rich potential as a setting. I could easily pastiche it with Alien... but...
I also get half a dozen harebrained campaign ideas a month... but most just drop off once I think about who would be willing to play.
