I like the 4th gen pixel art era. Games like Secret of Manna, Super Metroid, Chrono Trigger, FF6, Terranigma, Streets of Rage, Revenge of Shinobi, Sonic Trilogy, Mohawk Jim and Headphone Jack, etc. They still look great today.
So do Dreamcast games like Sonic Adventure and Shenmue & Soulcalibur.
Also I have a special aesthetic bias in my heart about Kikiri Village in OOT. Banjo Kazooie too.
In terms of graphics power, It would probably be a PC game like Unreal.
