The thing is the "secret public showcase" gameplay, I've seen it, is honnestly just not good enough for a public display.
Looks like a 2005 random fps...
Lots of work to do, obviously, CDPR won't admit it publicly either "heh sorry guys, the design part was fun but we struggle AF to make a fun game out of it".
The mission is about you, doing a deal with the voodoo boys, there is a few rp scenes (more like fallout 4, yes/no/maybe).
Then, the mission is basicaly basix, go there, shoot, solve the objective.
It's not bad in itself (if the game lengh is like 20h) but no way i'm doing this for +100hours.
Ok, it's still work in progress, and it's just a demo mission, but as it is, I join with a few people who criticize the gameplay mecanics, it feels super generic.
Honnestly, I still wait this game, but there's lots of work to do...
