I’m a huge fan of Evolve, an idle game played in the browser which only requires a network connection to start up. Saves are text that you can export and load to a file. There’s lots of strategy, all kinds of ways to play, and makes for some funny stories.
God damn that’s a great game. At the same time, I think they did this knowing that folks would die all the time, so they didn’t want each death to be super punishing.
