Now we just have to decide how the AI's Cleaners will handle these wrecks knowing you'll be back to add them to your fleets. Does the AI even make Cleaners? I haven't seen them make one yet.
It probably wouldn't be too difficult for the AI to make cleaners, as they could use the same logic as the human ones and it would be in their interest to not have these ships reclaimed. It is, of course, yet another thing for the AI to think about. Though now you mention that, maybe the AI could even make rebuilders to reclaim its own ships back. That really does make you go HRRRRRMMMM!
Actually, if the AI was using parasites itself, it would have to use rebuilders anyway. To stop things getting too complicated and confusing, maybe it should be the case that remains can only be reclaimed by whoever destroyed the ship or turret, not just anyone, with cleaners being used to remove them altogether. (I think this is already the case).
An appropriate and interesting suggestion--though would it affect turrets, as they already leave wreckage behind?
I imagine that this would affect turrets too. I quite miss being able to steal turrets. It was probably a bit too powerful before reclaiming AI turrets when attacking a system (especially with Leech Starships) as the reclaimed turrets did much of the work clearing the AI from around the wormholes. Allowing turrets to be reclaimed again with a bit more effort and delay might balance it out a bit.
As a further defense against this being too powerful, the rebuilders could stop working if they get decloaked by a tachyon emitter and automatically attempt to retreat to a safer place where they can't be seen.
What about supply (for the Rebuilder)? Parasites wouldn't be much use in areas without supply which kind of makes them even less useful than they are now.
Good point. The rebuilder would need supply, otherwise this would be exploitable. The wreckage would stay until it was either reclaimed or cleaned.
Slightly crazy idea follows:
Transports could collect ship remains (probably not turret remains) and take them back to a system with supply to be reclaimed. This could be a researchable ability, probably quite a cheap one, and could be enabled/disabled by the use of normal operations/low-power modes respectively.
Even if parasites were less useful in areas without supply, I still think that they are useful. The way I look at them is that you are sacrificing raw firepower for the ability to gain not just free ships, but entire populations of new types of free ships without needing to spend research points on Mk2 and Mk3. It's almost like getting extra Advanced Research Stations and even Core Fabricators and Advanced Factories but without the worry of having to defend those, which is incredibly valuable. Something that valuable really needs a few downsides
