I played some Valve games (like Half Life), but I don't use Steam out of dislike to any DRM. I can't say they were the most influential in the gaming industry. Id Software was much more, with their breakthrough into 3D shooters back in the day.
Regarding TW2 on Xbox. Unfortunately CDPR additional focus on consoles caused drawbacks in the gaming interface, which were partially addressed in subsequent patches and releases, but only partially. In general, TW1 had an interface designed purely for PC controls, while TW2 made compromises in direction of consolization, which made things worse. I hope they won't repeat this mistake in the Witcher 3, though it's not a trivial task to design the interface to be rich and comprehensive on PC, while at the same time having a fallback mode on consoles to work well with reduced controls.
