Here is a nice list with video's with all the enhanced games so far, great video's
I think I got them all, make sure to notify me if I missed any, I might add more games when they are available to this list if it doesn't get to massive :)

Also comment and let me know which one you think looks the best and which game you would love to see added, like red dead redemption, grand theft auto 4 or other games? Personally I would love to see the Fable games be added. Hope you enjoy these video's and make sure to not turn this topic into a console war, thank you!

Skate (new!)

Assassins Creed 

Mirror's Edge 

Oblivion 

Halo 3

Fallout 3

Gears of War 3

I'd like to play every Gears of War game in 1080p 60fps, that would be sweet.

Fallout: New Vegas is the best Fallout imo so that also. And Mass Effect trilogy.

Mass effect trilogy is a good one... If a remaster trilogy ever released I would have bought it and replayed the series. Might not have to!

The Witcher 2 and lost odyssey come to mind.

Yeah seeing how New Vegas had the same tech, it should be possible, ME is also on my wishlist :D

The Witcher 2 would be sutch a fantastic game to see enhanced and for lost odyssey the xbox one x already fixes the framerate issues so much from the original release I feel like its already a big step up, either way, would also be nice ofc ^^

I've tested a lot of games and most look noticeably better, even without a patch. Gonna give Mass Effect a try when I get home.

Yeah since they force texture filtering and obviously also increase the average FPS you get in the games, some of them feel and look so much better. I played a few hours of Red Dead Redemption and the Fable Remaster and it was like playing a different game from the original console release.

I would like for games that aren't found on any other platform to get backwards compatible.
I don't really care for the likes of Assassins Creed, Oblivion. etc'. I have a PC and I was thus able to play such games with great visuals that often exceed the Xbox One X re-releases up to a decade ago.

But something like... Infinite Undiscovery, Naruto: Rise of a Ninja and The Broken Bond, Viva Pinata, Blue Dragon, Fable 2, Kameo, Perfect Dark Zero and Lost Odyssey just to name a few would get my interest.
I know it's false hope with the Naruto games as Ubisoft has lost their license... But I can hope can't I?

Halo: Reach
Mass Effect Trilogy
Dead Space Trilogy

You're testing the first one? Let me know, that game never had the best frame rate on 360 and DF showed that it was worse on Xbox One. The X has a 30% clock speed increase over the XBO CPU, I would think that would make a tangible difference.

Playing it now. The results are not good. Maybe it's better than the original hardware but the game is a mess. Textures still pop in. Everything feels shakier than I remember.
