The lack of flops

If the Sinnoh game will get remakes and sell like 12m copies like ORAS did, i'm sure it can be the best selling generation since Kanto

But the remake wouldn't count towards gen 4

Anyway Gen 5's sales are probably a bit higher by now

and XY's aren't accurate (It's 13.99 million)
Plus ORAS is at 10.27 million

Sinnoh was my childhood Still have both P&D

Still the best and most enjoyable ones

The fact that I've played every single one except Alpha Sapphire/ Omega Ruby . I should get on that.

Diamond and Pearl are the best.

the remakes are the best though, the graphics

In RSE's defense the NDS sold way more than the GBA
They are still the best selling GBA games ho

Saaaaaaame

Gen 3 is still the best gen

Tea

Mess

The third gen was done wrong. It did not deserve those numbers

king diamond and queen pearl slaying!

Gen 4 >
