I got into FF like... 4 years ago. maybe 5.
I would say i have no nostalgia for the olden FF's but they definately are some fo the funnest games i have played.

I would rant about how games nowadays are made with no soul but im not sure this is the thread.
I will say though, theres a clear difference between games made 10 years ago and now. Nowadays its less content for more money. back then it was more content for the same price.
Not that all modern games are like this ofcourse, i havent played much but games like darksouls and stuff are genuinely greatly crafted games.
So... i'm not really too sure if i have a favourite time period. I loved playing games back in the day like Halo and pokemon and stuff, but they dont have the same impact on me as they used to. And newer games i have played are more fresh so i feel like i like them more, either way i'd say theres going to be bias either way. Be it Nostalgia or recency bias.
