Dota 2 is of note, but that was a pretty safe project being a straight remake of an already popular mod with the mods developer at the helm. Their major titles since 2012 were:

  CS:GO (remake of a remake)
  Dota 2 (remake)
  Artifact (flopped)
  Underlords (flopped)
  Alyx (good)
  Counter-Strike 2 (remake of a remake of a remake)
  Deadlock (early beta, but promising)

I think you grossly undervalue execution. Ideas are cheap. Most developers would have turned those games into weaker money extracting machines that generate one tenth the love from current players

Making remakes old popular mods is not a safe project.

Cs:Go was a 'remake' of cs 1.6, which was the original cs with a lot of changes and updates, but no remake
