TLDR: Its more Wartribe Academy, but a little different.
For the first chapter (0.1.0), there was more story content than I was expecting. I'm used to most games having fairly small updates, but this did play well. Not much in the way of animated scenes, so if you're mainly playing for that then I'd give it time to build up more.
As far as characters go, it is pretty much the same graphics, same animation quality. Sadly, where its early in development many of the characters aren't really in the game yet and because of the events at the end of the prequel, the tone is a bit different too as far as characters interact. I'm a bit on the fence with some of the changes but not letting it affect my review until more of the characters are back.
There is a newer UI and music, but I'm not a fan. it takes up more screen space and the font color forces you to run the dialogue boxes at higher opacity which means you'll have to use "hide" more if you want to see the bottom of renders. The music is also remarkably louder - I typically play on 30% volume in Wartribe Academy so I can also listen to a show or music. In Wartribe Origins I have to keep it on 5% and it still feels louder than I'm used to. I really hope the sound and UI wasn't a big part of the chapter development because that could have gone more towards the actual story instead of what feels like a cheap downgrade.
Really hope the quality keeps up with the original game, which was a 5/5, but with some of the changes I do worry it could slip from a 4/5 to being a mid tier 3-3.5 game.
