I agree with Katri. I love the current times we live in where we have access to more games from the past than ever, and also have an enormous indie scene that's more alive than ever, and tons of AAA titles that still offer really amazing experiences.
And having grown up in the 90's, I am a huge fan of the 16bit era of SNES, DOS and Sega MegaDrive. I just love how huge of a difference there was between systems then and how different games would feel on each system and how there just felt like more games were exclusive. You had games on Mega Drive that you would never find on a SNES and vice versa.
