I took a break from this one for half a year or so but plan to keep exploring some of the places this program has to offer.
I've been afraid to check for updates, the version I play was updated in early 2019. SIngle player only. The only thing it lacks is the ability to exit your vehicle as an individual. It may pilot like a flight sim but it is very Freelancer like with jobs carrying cargo, passengers, fuel, crew, etc. You can use autopilot or do the flights manually. Its also very "2001: A Space Odyssey" with the circular wheel space stations. Very nice detail with a great deal of accurate topography in some cases (like Mars). For those in need of a little space and new places to explore, this has years worth of area to cover. I've been thinking about seeing how long it takes to get to the other end of the map, around two thousand systems across! Free to download and play. https://pioneerspacesim.net/page/download/
