i'm in your conscience
Gen 1> Gen 2> Gen 5> Gen 4> Gen 3
Very, very close to my order tbh. It used to be exactly this, but gen III got a lot more popular during gen V it seems, with the hopes of remakes and suddenly it went from being hated to being "omg let's go back to Hoenn I loved RSE so much!!"
Though, I'd also put gen II ahead of I since that seems to be where most older fans stopped playing.
This is what I think:
II > I > V > III > IV
Of course, that's just me. I feel like II is more overrated than I since like I said, that's where a lot of gamers left off before stopping the series, or stopping there and picking up in a later gen. It improved on gen I, which I think a lot more people liked and then you get to go back to Kanto, where the gen I games took place. So Gen II has a lot going for it in ways of being overrated.
I love gen II though, so don't throw rocks at me y'all, lol.
I'm not gonna go over gen V rn, but I definitely agree with this and I'll also add that I think the plethora of characters we got in gen V lent a hand into it being overrated.
