To be fair if a game is 25 or 30 years old I used to be able to understand remastering it more so a 30 year old or more game .. I say used to as we are getting to the point not only are remasters reaching a critical mass piont but also now that games are getting made where there is a standard and one that hasn't changed sense about 15 years or so now, where accessibility is no real problem for older folks and those with physical handicaps... compared to before and graphics hasn't changed too much .. thus I don't see remasters as needed unless a massive shift in standards happen in gaming and a massive shift in accessibility.. Only way I am okay with remasters now if they iether have been gone do to rights issues for so long or they are so far back like say the 90's or so that a remaster is needed

good
crysis is just a very outdated tech demo , as a game it is boring and pointless
cnc4 probably there is no human who would miss that crap

Crysis apparently has issues with SecuROM activations. Origin and GOG releases are still purchasable.

C&C4 was taken down due to the recent eFootball 2022 failure stressing attention at worst-rated games on Steam, of which C&C4 was ranked #4 (#3 before Konami did a bad). Also its servers have been in a state of failure for months. The Origin version is still purchasable.
