I'm feeling sad cause I had to skip all 7th gen :x, from 2010 to 2017 I just didn't played any console game, only some PC free games and the handheld games I played on Nintendo DS. I reentered in gaming world very late in 8th/current gen (could only buy a 3DS once I got a paid job so yeah, very late).
I'm also familiar with some (many) 4th gen titles from Sega, Game Boy and SNES because they were all very classic and had many versions for late consoles, though I could play SNES and Megadriver myself because my had both neighbor and I used to rent them. I still thinking my knowledge and experience from those gens (4th and 8th) are pretty limited
But I followed very religiously the end of 5th generation (Playstation 1, Nintendo 64) and almost all 6th gen thanks to PS2, even if I was a child back then. Ngl only got a PS2 in 2004 (it was released in my country in 2002 only) and completely ignored 7th gen existence until a friend show me a kinect when I went to college in 2013 I guess.
Both were 5th and 6th were awesome for me and I have a huge nostalgia to PS1 games
I still have to choose 6th though thanks for PS2. I remember playing God of The War for the first time, what a game! And this shit played all my PS1 games plus my DVDs as well. I'm very attached to it cause I needed to survive with PS2 only for like 6 years until I finished my first gaming life cycle (I stopped console gaming as soon I hit adolescence)
