So if it was exactly the same, me being able to drive would allow me to 'fix' that stuff on my own.
I'm not sure, it might make things a little more hard on the PCs (considering refuelling is already relatively expensive as it is, plus the cost of owning an actual vehicle).
Deathball Simulator, would require the devs to define Deathballs rules.
Alternatively, if deathball is able to be played by norms, can we get a corpsec deathball league?
Riot Gear Variant with NPC's:
Street Gear might be a good thing to call it. But basically a riot gear like setup with two factions, Terra and gangers, where there's NPC's inside of it that are at the various "tiers" of play. From Gang Kingpin all the way down to shopkeep and corpie jumper level NPC's.
A clothing design simulator, maybe call it Juicy Vee's Closet or something.
I have no idea how viable it would be to implement, but SHFL Simulators to show off less-visible mechanics to new players (piloting, driving, rigging) would be fantastic to advertise Sindome's systems to players who might otherwise not get to experience them, and give an avenue for learning them in the bargain.
As hacky as it might be, something like a 5x5 cube of rooms off of SHFL with indestructible demonstration vehicles that characters could use first-come-first-serve basis inside of it, might be a way to show those systems off without going to the lengths of developing an actual 'game' with them.
Though instead of bumper cars I might make it a race track. Frankly, there is a LOT of ic space on the Mall roof. You could totally put a small race track there and still have many rooms of parking.
