What does "done" mean? If software does what it should do, has implemented all goals in development and does not need maintenance, then it is done. However, the more complex software is, the more likely security fixes and compatibility fixes need to be done.

The solitaire game that came with Windows 3.1. Certainly that’s done.

Why is the game "done"? It does not work on modern systems anymore, does it? I don't get what "done" means for this game.

Super Mario Brothers is not only done, but also awesome.

How is it "done"? They released the game and it still has bugs and does not run on modern machines directly. The fans added lot of features through modding that the game could use to have. It's just abandoned and not updated.

I don't get what "done" means here. The given examples are a bit weird. Sure games are easier to be declared as done, than "regular" computer software on PC in example. Games for old consoles off course have not the same security issues as on modern PCs in example. These examples are more like "abandoned", as their platforms are.
