Everything on the left prior to 2003 (which looks like everything on there other than Dragon Quest IIRC) was just SquareSoft. They began going downhill in the spring of 2003 when they actually merged with Enix.
IMO, Dragon Quest is the only game Enix made that was actually worth a shit and it still paled in comparison to the likes of Final Fantasy. It sucks that instead of Square elevating Enix, it just feels like Enix drug Square down.
Also, wtf is "Various Daylife?" That one sounds more like it could be a competitor to The Sims and not a JRPG. lol
I think your opinion on Dragon Quest might be a bit unpopular. Its a very popular franchise in Japan specifically and I have personally always liked it better than Final Fantasy.
