I didn't make it!
4 Players is nice, but more is even more fun. Also we should be able to make an Empire vs Empire battle of course. We need up to 8 player bigger maps, and maybe an option if 1-4 people share a space station, so 4 players can do with 1,2 or 4 space stations. That's also why you need bigger maps... Might have to do with more traveling, but space is big :P
What migt also be fun is different nebulas, they already distort sensors, but what if they boost them, or boost weapons, or disable weapons, or enhance armor ? Might be fun :)
