That list of new titles includes the full Splinter Cell series from original Xbox, plus Xbox 360 favorites like Skate, Prince of Persia The Forgotten Sands, Enslaved: Odyssey to the West, and others. There's also a slew of Xbox 360 games getting updates to look better on the Xbox One X covering the Perfect Dark series, Viva Pinata, Kameo and the Banjo-Kazooie games.

DLC packs for several Xbox games (including both Star Wars: Battlefront releases and the Splinter Cell games) are now available to Xbox One players for free. Better yet, the awkwardly-received Too Human (remember that one?) is not only part of the catalog, it's available digitally for free.

Now for that bad news. That list of games represents the last of the titles Microsoft is adding -- ever. Now that the company is focusing on making sure Xbox One games play well on future, hardware, "we have no plans to add additional Original Xbox or Xbox 360 titles to the catalog on Xbox One, but we're excited to continue our work on Xbox compatibility across platforms and devices, which remains a top priority."

Hopefully the 600+ games already listed are enough to include your favorites, but some of us will have to keep a working original Xbox around just to satisfy our Rallisport Challenge 2 urges.
