First, this is a GREAT game. It’s been a long time since I played a good game. I also enjoy that it works on my outdated computer. And works well.
If there is one thing that I feel that this game is lacking. It would be the lack of freedom of ship movement.
Why not make each sector bigger? The gravity well can stay the same size. But why not make the non-gravity well area of sectors a lot bigger.
This would allow hiding fleets, and maneuvering around. Give more freedom.
Also, you should be able to stop anywhere along a warp line. Like in Freespace. This would allow hiding fleets and offering more options. Say if you had a ship that disrupted the warp drives of other ships. You could then set up an ambush along a warp line.
Again this is a great game. And I think the best way to make it better is to offer more freedom in ship movement and tactics.
These are just some ideas for a sequel. As I know these are major changes.
My thoughts for improvement to an already great game!
