I've seen the comments about build costs increasing for more than 2 stations and haven't waded in yet but I think I will now.
Most of the complaints seem to be suggesting that it's bad because there's no clear indication that this is how it will work, both beforehand, during and after. I agree with that. But this is Elite Dangerous and I'm amazed some of you aren't already acutely aware that this game doesn't do "in house" very well, in general. That said, I think all of the data should be available in game. Even just deciding whether to build a type of ground settlement demands that you fly to a surface... just to browse the options, costs and related benefits! This is not good.
But... and I stress this again... if there's a game on the planet that heavily relies on third party support (to the point where I'd say most players outright love it for that fact), then this is that game. I don't like it, nor have I ever. But it's just how it's always been and I doubt it'll change with this new feature. Nonetheless... I wish for this to not be the case and so would fervently support better in game data/documentation. I'm just tired of asking for it, having spent years doing so with little success.
My issue with the complaints so far is many have said the above but... it's clear that wouldn't make them happy at all, so why mention it? Like, the paraphrased argument of "this is ridiculous! Why can't we just do what we want? It'd be OK if it was even made clear to us! But it's not!" to me just reads as "I want to do what I want". The part about obfuscation is irrelevant to that person. Hard disagree with that sentiment because I lump them into the below category of complaint.
I think a soft cap, which this is, works better than a hard cap (which some have suggested would be better, but I have no idea why). No one said, before this went live, that we would be able to blithely blast up 25 stations in a system and nothing else, if we decided that would be fun. The feature needs to work well within the framework of the game. This soft-cap means systems will be balanced. You still get the option to build lots of stations if you desire, but you need to balance it. A hard cap of just 2-3 stations wouldn't work either, because then you'd still have players throwing up three stations with no infrastructure to support it. This is obviously aimed at achieving balance across systems, which is based on the game's existing framework. Anyone just saying "let us build what we want!" don't seem to me to be particularly interested in any of that and I simply don't think it's their call. The number of configurations commanders can utilise within their own systems is hugely varied, despite this soft cap. I think asking for the soft cap to be removed entirely is unreasonable and I don't support it.
The only argument remaining is whether doubling the cost is reasonable. And to that... I can't argue either way. It's not my game, it's FD's. They know better than I do as to whether that's right or wrong. I think players asking for scraps (i.e. conceding that the soft cap is required but just want it to be reduced so they can build more stations) are welcome to ask but I fail to see why it's so important, either. That said, if FD agree and reduce the scaling then, cool.
I just don't see it as a huge deal breaker, either way. It is, by far, the lowest concern I have with this feature.
