I wonder what will happen when SQEX will have not powerful IPs left, because of mobile fidelization is harder (and I cannot imagine doing remake of Million Arthur Kings, or those IPs lasting for decades) and FF and DQ slowly faded as their fanbases grew up.
Well, their current set of mobile hits is:
Really Big:
-Dragon Quest Monsters: Super Light (console IP)
-Million Arthur 2 (mobile IP, sequel to account for the switch in how the feature phone to smartphone game market evolved)
-Final Fantasy Record Keeper (console IP, DeNA made/published)
-School Girl Strikers (mobile IP, first entry)
Moderately Big:
-Sangukushi Rumble (new IP, first entry)
-Dragon Quest X Companion App (this isn't exactly a game in the strictest sense by a tie-in service to the MMO)
There's a variety of smaller hits that go in and out of the top 100 chart like:
-Pictologica: Final Fantasy
-Final Fantasy: Legends
-The Irregular At Magic High School: Lost Zero
Beyond that I'd consider the titles to not be big enough to really be hits for a company the size of Square Enix. Maybe a smaller publisher like Sega.
They do seem to generate some original hits on the platform. I'm curious to see how they follow up this fiscal year though since it was way more successful for them than their previous ones with a hit rate of maybe 40-50% of their notable apps released, which will be a hard feat to repeat unless they've really figured out the market.
That said I don't think a lot of these games will have sequels unless the market changes enough that they need one to stay relevant (see Million Arthur), so it'll be especially interesting on the basis they have to launch a whole ton of new games that are essentially planned as 5-10+ year services.
Just wanted to add, for those not informed about Square Enix's reports: HD Games include both home and handheld games.
I'm unsure which of the other two categories f2p PC games go under (Nosgoth, Heroes & Generals), but they bundled under a non-obvious name as well.
Edit:
Correction, as 1st Course points out, f2p PC games are under HD Games.
