My opinion may not best as far as objectivity is concerned. I was never a huge gamer. The number of overall titles I have played were few and decreased in frequency as I have gotten older.
However, I think my favorite games have delivered more pure fun factor through the years. Thinking back and considering like Super Mario Bros for the 16-bit Nintendo, Mortal Kombat for XBox, Madden for PS1 and PS2, Sonic the Hedgehog for SEGA, Zelda and Rogue Squadron for Nintendo 64, Batman: Arkham Asylum for PS3, etc., I have been more and more wowed by the look and degree of gameplay as game consoles have evolved.
In fact, the only games I have played over the past five or six years has been Star Wars Battlefront I and II for PS4 and PS5. Shoot. I have logged about 4,300 hours between those two games alone. Fun? That would be an understatement for me, lol.
