Elite: Dangerous is an MMO that is widely regarded to have the largest video game map in history with the overworld being an 1:1 recreation of the Milky Way galaxy. Distance traveled is measured in light seconds/years and the such. Without the Frame Shift Drives in your starship, you could take months of in game play to travel from one planet to another in just one system. There are over 400 Billion visitable systems in the Milky way, including Sagittarius a*, the black hole in the center. Making the trip to and from this black hole takes roughly a month of on and off in game play depending on your ship. If you die on the way, you have to start all over again with no progress saved.

This is the Distant Worlds Expedition. 1,100+ people signed ledgers to venture off to the farthest star visitable in the game. A place twice the distance of Sag A. The trip takes FOUR MONTHS of nothing but jumping from star to star. They are almost there to this day. Almost to Beagle Point. They're been gone for three months and have kept an extremely tight schedule. Free time IRL has been stripped and only the insanely dedicated will make it. more than half of the people that set out on this journey have DIED.
Since the game allows for PvP in any place of the galaxy, you can imagine their horror when at roughly 30,000 Ly from home, having all but one body guard dead for the entire fleet, suffered a mutiny. While at one of the waypoints, one of the wings (a group of players that are flying together) decided to open fire on these defenseless explorer ships. People died, exploration data and months of dedication were lost, there was panic, and this one ship managed to take down all the pirates. He'd run dry on ammo and had one target left. From what I heard, he put all his guns away, put all system power into his engines and goddamn kamikazied himself into the last pirate, saving the fleet, but forfeiting his share of the data spoils.
The expedition is still on and the only reason the players are still there is because of that one brave soul.
