Yep, Nightreign is a standalone co-op focused rogue like version of Elden Ring. It uses a remixed version of Limgrave and selectable characters with unique abilities and much faster movement speed to focus the game down into 1 hourish "runs" with many random elements. You can also challenge it solo if you want, but the story will be completely disconnected from the regular game as it takes place in a "parallel universe." This also kind of explains the one bit you understandably didn't pick up on, there are actually characters, enemies and boss fights from the Dark Souls series mixed in as well (plus some ideas and mechanics from Bloodborne and Sekiro) so it's sort of a Fromsoft Soulsborne mash-up set in the Elden Ring universe. Onimusha is.. weird. It started as basically a survival horror Resident Evil game set in Japan with samurai and freaky monsters instead of tactical police and zombies. As the series went on, though, it became much less survival horror and more of just a straight up action game. Then it basically disappeared (for over a decade IIRC) so it's anyone's guess what the new one will be like. As for what I'm personally most excited for? It's probably a tie between the new Okami whenever that does happen to come out and the new, revived Ninja Gaiden game that they showed right at the start of the pre-show. The series has been both excellent in 2D and 3D form but hasn't seen a new iteration in a very long time.. but now it's coming back and in a modern day variation on it's 2D origin. What they showed looks excellent and not just a prettier retreated of what the series has already done.

I think they had a lot of good games on show this year. I haven't ever played the Ninja Gaiden series, but the trailer looked pretty.
