I love the robots... especially that it serves as an explanation for 'respawning' after death...
Personally, I like survival mechanics, but I can see how power/oil (or, air/food/rest etc. if organic) would detract from the theme of the game; building spaceships. It's not 'fun' to babysit a bar that is constantly depleting with no benefit other than "now your allowed to continue doing what you were already doing without death" .
Now, if there was some sort of gain, that isnt game breaking? For example, different endo "frames" that must be crafted and maintained? Like, a frame with a faster jetpack, but now you have a propellant tank in your abdomen, so you need to keep it filled, and explode upon death? Or, a interceptor frame, with a further "magnetic feet" threshold, but requires you to maintain power/energy? Or even like Community Manager Ella suggested, a frame with more arms! Although, I'm not sure mechanically how that would function/control; but maybe it's simply some cosmetic flavor, and that frame has a larger inventory, and can carry additional weapons Etc.?
Of course, on top of maintaining some suit resource, they'd be much more expensive to lose, too.
To sum it up, I'd like to babysit a survival mechanic if it gave some sort of benefit for doing so.. and then the 'basic' resource free endo would be for when you're starting out, died and ran out of money, want to peacefully design a ship, or just chill/chat with friends, without having to babysit a hunger/power meter.
All that said, if the game hypothetically doesn't do as well as I hope it will; and gets reduced to privately hosted servers etc., then id hope that some sort of organic NPC common enemy is introduced to keep the smaller playerbase busy. Or even if it does do well (as it should!) then introduce a similar ideal well after EA, and all other planned features have been implemented.
Just my 2c.
