Are you going to tweak the store rare item availability? There’s a few things I don’t think I’ve ever seen in store (++ Damage AC/10s and Medium Lasers for instance).
Honestly I'm tempted to remove all the +gear and make vanilla gear the specials in the stores that only sometimes come available. This is the Periphery in 3025. There's 55000 mechs in existence and only 8% of those are in the entire periphery, parts should be something to scrounge for. Most worlds are 100,000 people huddled around a single spaceport, I'm thinking the only thing that should be in the default store is machine gun and maybe AC ammo. I want it to be a fairly agonizing decision whether to salvage a weapon or a mech part, which is why I want to eliminate the random salvage altogether.
I may be a masochist.
