I think this is the proper way to treat games that you’re done developing. My only requests might be:

• Adding a way to self-host an instance (with mod tools)
• Open sourcing (so the community can fix their own bugs)

Not FOSS, but ad free and its been able to find the hidden RSS feeds for things OK. FeedDemon at: http://bradsoft.com/

Probably not what you are after, but maybe someone with a similar question.

Factorio is a dangerous, but very fun, suggestion =)
