As someone who is a fan of the Dynasty Warriors series, this game brought back a ton of nostalgia. Besides the amazing graphics, the fact that Koei Tecmo goes to the past Dynasty Warriors games and uses those elements was a surprise to many people.
For me, what surprised me the most is the gameplay. When I played the demo, I was happy that they brought back the classic battle overview map and conditions. Playing it also felt like it was an open world. Pretty surprised that open world didn't really work out well for Dynasty Warriors 9. For some reason, Koei Tecmo did an awesome job implementing the open-world element in Origins.
Overall, as a huge fan of the series since Dynasty Warriors 2. I'm glad that Koei Tecmo made this game. Many fans of the Warriors series are coming back to play it. Brought back a lot of childhood memories for me.
