The proposal made by the OP leaves itself open to real world sales. The OP explicitly describes a system whereby one player can transfer assets to another. That transfer would benefit the player in question and where there is in game benefit to be found, you will attract players that will make real world profit from it. Its a problem that has affected many online games. The developer has to consider issues like this, before they put content in place, even if only for their own PR and brand protection. FRONTIER have explicitly state that they do not wish to create content that would move Elite into a pay to win situation, or to create real world markets for in game assets. It is their stated business decision.
The 'idea' of being able to steal ships may indeed be fun. As would many other ideas that involve players genuinely competing with each other in ways that aren't just shooting until blown up and then getting a nearly free ship back. However the developer must consider a much wider range of issues than just "hey that sounds like fun". There will be hundreds of potential ideas that have been discussed durign product development that will have been shelved for precisely this reason. There's is anything remotely technical difficult in implementing the OPs ide , but you have to understand it's potential impact on the wider game......
Have fun.
Well, ignoring the last paragraph and get straight onto the point... (points)
ED is well aware of the pitfalls of on line profiteering and don't need a voice on their shoulder to point them out, they have brains and if they want to work with an idea then I'm sure all of the 'transferable funds nonsense' will be dealt with by them,
I see the suggestions forum is just for suggestions, as we have no power other that to say..."please sir can we do this?" not really for working out every single detail and pitfall by the thread author, and as this one is just three line of suggestion it could really do with expanding upon.
This is where we come in,
firstly there is no mechanic (as far as I know) that would allow us to tow another ship somewhere, but the autopilot delivery bit could work perhaps like a delivery 'over a period of time' or perhaps a wing type 'thingy' in place... I don't know, any ideas?
I see the 'sold for profit bit as a red card for some here, but there could be some proviso's that the OP perhaps hadn't though of (or even wanted) that could curtail massive profiteering.
Perhaps the registration or re-registration of a vessel that has been used for unsavoury purposes might have to please several authorities whereby it's ruddy expensive to clear the registration, and perhaps it might be cheaper to fire it into a shipyard as salvage for parts... this would see much less profit go the 'new owners' way
Perhaps the thought that the A rated drive in the big ol' hunk you just saved is gonna cost as much as the ship to replace... the scrap value might not actually be worth that much is you did a poor job of getting the thing to stop.
If ED drop legs on us (yes I still consider myself part of the playerbase despite my thoughts on the FSS) it will almost certainly have something like ship boarding in toe to toe combat, thus capturing a ship might not be so far a stretch of the imagination as we think now.
Anyway food for thought there!
