If you don't mind 2D graphics and no multiplayer, I would recommend playing Starsector. It has pretty much the same basic gameplay loop as Elite, but it features more complex combat + ship mechanics, a more dynamic world and it allows you to setup your own colonies on newly discovered planets. Also you don't need a powerful machine to play the game, it's runs flawlessly on my laptop in 1080p (Fedora + Intel HD520).
