Back in the 90’s, Ambrosia Software released a series of space RPG / trading / combat games called Escape Velocity. The creator of the second game, EV Override, is now running a Kickstarter campaign to remake/remaster the game for modern platforms, starting with Mac OS X, Windows, and Linux.
Aside from the base game, the remake of Override will be compatible with existing fan-made mods (which there are already decades of, including some fan scenarios that are full-blown games in and of themselves), and it's also designed to be easily and extensively moddable.
For those who are interested in checking it out, contributing, or spreading the word, here’s a link to the Kickstarter campaign: https://www.kickstarter.com/projects/cosmicfrontier/cosmic-frontier-override/
Also, attached is some concept art of what the ships from the original game could look like with updated/modernized graphics.
