Edit: Updated mirror copy to include Spectrum post edits.
Haven't read it yet but I have to say one thing: they posted this in the stupidest way possible. Med gameplay changes? Proper article on the site. Engineering? Spread over multiple posts on Spectrum.
Why?
Edit: Well, I read through the whole thing. Sounds alright though I'm not a fan of some of the ideas (their approach to redundancy for example). It's just text so I'm not going to cast my judgement until I try it out myself.
Other than that, I hope this leads to finally having some proper money sinks - not huge ones considering tuning it for constant replacements would be extremely annoying but it's a start. Also provides something to do with the ship beyond using it as a transport.
Now if only they could do something about losing ships when the game crashes.
Wear will be tricky. Why would i want to play like that if i can just file a claim on my lifetime pledge ship... i can see the appeal, but that might have to be reworked
Keep in mind claim timers will be increased a lot in the future, especially for larger ships. In the past there were also talks about variable timers depending on the economy (some ships might take longer than usual for reason X) and other effects when claiming too often. No idea if/what will make it into the game but they'll most likely tune it so dropping a few k UEC will be a faster option.
Plus, we'll hopefully be able to bully them enough to make the rate of wear reasonable enough not to be annoying.
