You thinking that something can't be improved on is not a good reason for it to not happen.
I remember over a decade ago when people were whining about a rumored Silent Hill 2 remake (long before Bloober Team even existed). The argument was as presented here: They shouldn't do a remake because it can't possibly be as good as the original.
You know what I have to say to that? A Silent Hill 2 remake would not erase the original from existence. So who cares? If the remake ends up sucking, go play the original. Simple as.
Funny enough, it's an even more effective thing to do today in regards to Steam games. For example, it's really sending a message about the state of Payday 3 when Payday 2 has several times higher 24 hour concurrent player peaks. It really makes it clear that people wanted more from the franchise and were simply unhappy with the newest product.
For real, this. The remake was bad? Oh no, good thing the original is probably still very accessible over multiple platforms these days.
You ask me, the problem with remakes is that the industry isn't focusing on games that aren't as easily available and could genuinely benefit a lot from a facelift and some tweaks under the hood. Stuff like Parasite Eve, where the original media also feels sort of timely or relevant.
That's almost never a thing with remakes. Counter-Strike 2 replacing Counter-Strike: Global Offensive is the one that would be most recent and is probably why you're saying this. If not, you're probably thinking of similar such soft relaunches after large updates (which arguably applies here, though the change is so substantial that they really shouldn't have outright replaced CS:GO).
That's a completely separate issue and should realistically have no bearing on whether or not remakes should be made. You should focus your anger at the true problem, which is that Games as a Service is fraud. Don't let them entangle your feelings on this such that you accept things like a remake replacing an original game as not only normal, but also an inevitability.
Jsyk you can still play GO by going to the available betas/releases in properties on steam. Totally agree that it should have been released separately, but with the skins being the way they are they would have had to port them somehow or the player base would have gone fucking insane.
Dang man no need to go full gung ho misundstanding on what op is saying. It's just theoretically speaking...chill the fuck out. I'll go ahead and say Halo 3 for my answer.
