RockPaperShotgun is carrying a keen writeup on Commander Genius, a new mod that upgrades id Software’s classic platformer Commander Keen with modern VGA graphics.
As you can see in the comparison image above, the difference is dramatic. The mod is compatible with the first three Commander Keen episodes, and the team is working to extend the functionality to the rest.
Download links can be found on the Commander Genius site. The Commander Keen anthology itself can of course be purchased on Steam.

Well, this is interesting! Nice to see support for Open Source games from people at Bethesda. A sign for continuing the Open Source policy at id?
