GeraltOfRivia_PL: I am curious what d'ya'll think
No idea, but there IS a group of Cyberpunk junkies out in the West.
I played my first game of Cyberpunk over 25 years ago (might even be over 30 years ago). We had a bunch of D10s and the cyberpunk RPG.
Since then the crowd of gamers has grown. I think anyone who ever played the TTRPG may be excited about a CRPG release.
Add to that Shadowrun fans (yes, they have their games already, but this is somewhat closer than many other games that sport netrunning and cyber enhancements) and the available crowd is already large in regards to those looking forward to this game.
Science Fiction is also very popular with PC gamers (I'd say more popular currently) in the West in general, so I think it will do well.
AS good or better than the Witcher III...no idea...but possibly.
