I had planned to keep that view, possibly a bit larger. I'm going for scale here without having 8000x8000 layouts which might cause performance issues for people, so planets, suns and other stellar bodies are quite large, so ships need to be small in comparison. I'll consider making a zoom feature though, or making the initial viewport a bit smaller so ship sprites can be larger without making the system feel too small. Most battles will involve three to five ships and as you progress into harder regions of space, battles will contain 10+ fighters and a larger ship for back-up. There will also be occasional pirate incursions into systems they share borders with that will contain more, so a more distant scale works best, I think.
It is currently planned to only be single player as I'm not an expert on network security and connections, and would rather put all of my efforts into a single player game for immersion purposes. However, if I raise enough funds, either from release sales or KS backing (when the time comes), small-scale, cooperative multi-player may become an option.
