Summon Night 6 is also a game that can sell well.
World of Final Fantasy is a bit tricky. It can be a hit or miss.
Ya, kinda having somewhat high hopes for Summon Night 6. Summon Night 5 sold rather well for a dying handheld on its way out. Well, World of Final Fantasy is Square Enix's first final fantasy for Vita, so hope it does well enough for more vita support from sq-en.
Final Fantasy X / X2 HD Remaster was the first Final Fantasy game on PS Vita and It did really well. ^^
Maybe that is the reason why we are seeing a better Square Enix PS Vita support! Will be interesting to follow upcoming Square Enix games on PS Vita (Dragon Quest Builders, Dragon Quest Heroes II, Saga Scarlet Grace...)
Actually a GAF insider said that FFX/X-2 performance on Vita is exactly the reason it gets more support (and he/she said it before Square Enix starts the PSVITA announcements).
