You can't leave it, planets are connected by gates, or you can actually spend Real world time, traveling between them and not use the warp gates.
Which is really dumb as the most of the ships don't go faster then 24kms 🤣.
I consider it a retro game... it supports glide... It also runs on linux too.
Which is rare for an older game, heck its rare for games now.
This is one of the rare space sims where using 2-Flight sticks is a must for accurate control too.
