My favorite Space Sim is Galaxy on Fire, and just look. There will be a sequel.
It really looks beautiful so far and I'm curious to what new elements the sequel will bring to the table.
What I wish to see is more open sandbox games and trading during the main campaign. In the first game the sandbox only opened up after you beat the main campaign, but after that there wasn't much of a goal to keep trading.
You can find the full press release here.
