And why only original releases? That's irrelevant nowadays, they can now be played on the ps4.
Do you want to have a conversation about this or not? We are talking about all of the time that passed between Kingdom Hearts 2 and 3. We aren't talking nowadays. We are talking about what happened during those 13 years between 2006 and and 2019.
Well, if you really wanted to play another home console-quality KH game after KH2 released, you could have at least tried out Birth by Sleep, which came out in 2010. Yes, you had to get a PSP (but even if KH3 had released during the 7th gen, you still would've had to get a PS3 to play it, so it's basically the same situation), but you could have got an experience practically in the same level as KH1 and KH2 without having to wait 13 years. Also, in 2008 (only 2 years after KH2), we got Chain of Memories on PS2, so you didn't have to get another console.
