The premise that I’m talking about is grinding, where you repeat previous stages over and over just for the rewards. It can be a bit boring but people do it because the rewards are worth the effort.
Games that I have direct experience with that do this are (off the top of my head) Final Fantasy 1 for NES (1987 release), more Final Fantasy for all PS (FF7 released in 1997), Diablo 1 and 2 for PC, MSF, Pokémon Go, WD: Our World, and Clash for mobile, Pokémon for Gameboy (1998 release). I’m sure Sega, Xbox uses grinding where appropriate and I haven’t played WoW, EQ, Eve, or Lineage before, but they definitely grind.
Yes, Scopely can add a button that lets you finish an entire rm or even auto war for you so you don’t have to even turn on the game for the whole war weekend, but that’s not what gaming is.
