Naturally, I guess I'll throw in some "oldies by now" from PS1 (if you can get a hold of them, some obviously readily available):

• Vagrant Story (Good Luck)
  
• Parasite Eve (Good Luck)
  
• Final Fantasy 7/8/9/10/10-2/12/Tactics (PS1 / Steam / Mobile for some)
  
• Castlevania: Symphony of the Night (Used to be rare, but can get it on any platform now)
  
• Chronotrigger (Easily acquired, on Mobile also)
  
• Legend of Legaia (Good Luck)
  
• Legend of Dragoon (Good Luck)
  

These 5 alone will be massive time sinks. 

• Mass Effect Trilogy
  
• Dragon Age Inquisition
  
• Witcher 3
  
• Persona 5
  
• Nier: Automata
  

If you want some open-world goodness:

• Fallout 3 / New Vegas / 4
  
• Morrowind / Oblivion / Skyrim
  

MMOs, if you haven't tried:

• ESO
  
• FFXIV
  
• BDO (Very grindy, be warned. Very beautiful on PC or straight up Runescape, depends on your rig)
  
• WoW, I guess, I quit a long time ago (Classic available now apparently)
  

I could list more, but I'll be here all day; I just listed what I felt like typing lol. I love games too much xD
