I see no reason CDPR should be concerned about following the spirit of action games. After all, they're making an RPG. Those come in variety of types though admittedly, action based seem to be dominant lately. I think it's mostly because large devs think that it will attract the shooter fans to play RPGs thus broadening the market for their product. I'm not that sure about that - RPGs are unlikely to please the action game crowd because they involve way too much talking for their taste anyway.
