I'm little bit curious to know some other game studios which supports (for free) theirs singleplayer game released 5(6) years back. Can you please give some examples?
Difficult to tell if you're sincerely asking or using a rhetorical question to be tendentious. Either way, the honest answer is no game studio has released a free remaster of a 7 year old single-player game. But then again, neither has CDPR. That makes the assessment "just another game studio" rather accurate in light of the fact their remaster was just delayed indefinitely.
Brass tacks, to date they have only
talked about a remaster, and only to describe a package of glorified mods. No mechanics re-design, no engine overhaul, just ray-tracing, textures, improved load times, and some throwaway armor DLC. Other gaming studios who commit to remastering games may charge money for the end result, but at least the result is substantive and... you know... real. The economics of game remastering do not bode well for the end result here if CDPR sticks to the free-DLC approach. There's a reason Mass Effect charged $60 for a decade old trilogy -- doing good work is actually expensive.
Coincidentally, CDPR only started
talking about a re-release of their signature RPG since the Cyberpunk debacle. Their brand took a bath after they launched a game they'd knowingly misrepresented to
gaming journalists and bloggers* and, yeouch,
their own investors. Ironic for a game about rapacious corporate greed, but that's another topic. All I mean to point out is this
thrice-delayed remaster was brought into this world as a PR tactic, and it shows. For point of reference, production of Mass Effect Legendary commenced in 2019, was announced in November 2020 and released in May 2021. 6 months between announcement and release of a full-blown remaster of an RPG
trilogy. Whereas CDPR is up to :checks calendar: 18 months from announcing a "next gen" reskin of lighting and textures.
[...] This company does not deserve any more patience and support beyond what they earn with finished work, ok? They're not overhauling, they're aggregating tweaks that basically already exist in the mod community. There's this common refrain that fans who are frustrated have lost the plot and delays are somehow good, "Take your time guys. Get it right." This is comically, tragically detached from what's happening, which is development hell for a patch (literally DLC) of cosmetic changes. So, sorry I'm not sorry for calling them out.
*Interestingly, this OpenCritic article described in very specific detail the bizarre requirements CDPR foisted on reviewers in pre-release that made it clear in retrospect they were attempting to mask significant performance and gameplay gaps from reviewers, but the article was taken down.
