Linux support?
A native Linux build should be available at launch and kept up-to-date with the native Windows build.
So Star Ruler ceased updating after I bought it in faith it would get better with time. And now I learn there will be Star Ruler 2, which no doubt I would have to purchase to enjoy. Figures.
We're sorry you feel that way. We regularly patched the game from August 2010 to October 2011 and the last patch we pushed was in August 2012. In total, over 30 patches were released for SR. The majority of those patches added free music, art, gameplay enhancements, UI overhauls and etc. in many cases beyond what was promised on the features list. If all this did not make the game better for you or satisfy our promise to improve the game, we apologize -- we took the game to where we felt it was complete though we recognize it is by no means flawless.
As for Star Ruler 2, many of the things we are doing in SR2 are simply not possible to do in SR1's engine. This is a large part of the reason why we began from scratch with SR2 rather than TC/Expansion SR1.
Will the game be able to handle a realistic distance scale any better than SR1?
Starflare has much greater precision than SR's engine -- as a result, it can support vastly larger distances (SR: single precision floats for positions; SR2: double precision floats for positions). However, 'realistic' is a matter of interpretation. Real distances in space are so mind-numbingly vast that a single true-to-scale solar system would end up larger than the largest galaxy you could possibly play in the default game. So, can the engine better simulate realistic distances? Yes, it is more capable of doing so now. Will it be able to simulate 'true-to-life' distances on a galactic scale? We're afraid not.
More stellar objects?
We'll release more details about the game world closer to release.
Multiple galaxies?
Will get back to you on that.
Will there be more realistic weapon ranges? (e.g. no maximum range/diminishing accuracy over distance)
It's much more realistic than SR1 however projectiles must expire at some point; if they did not the simulation load would become impractical.
