As far as mobile games go, it's mostly freemium of course, but as far as freemium games go, I've been enjoying the shit out of Final Fantasy Record Keeper.
Essentially, the story is you're what amounts to a librarian that's on his first day…and boy what a first day! The library of all Final Fantasy world records is raided by some unspeakable darkness and the stories have been scattered, putting the multiverse in disarray.
So it becomes up to you to travel to these different realms and recapture the story "memories" to restore the records.
Gameplay wise it's old school turn based RPG with a party of 5. Everyone is limited to a weapon/armor/accessory slot and two ability slots. Your party is made up of different characters you find while discovering the records. Each character is empowered when fighting in their own realm and items used in their native realms are also empowered.
There's limit breaks and this is really where the freemium comes in. Every character has their own "Soul break" to start, but acquiring unique weapons allows you to unlock new ones. You can do it the slow way by gathering mythril to roll the dice or you can pay to roll the dice more often.
Anyway, what I love about this game is it's sufficiently challenging at higher levels, customizing your team is actually pretty engaging. Every realm uses music from the original games. While choosing a record to engage, you hear the game's "overworld" theme. During combat you hear the world's combat theme. It's glorious.
Not just all, they have frequent events that allow you to pile up items and upgrades as well as catch up if you missed a specific character's event to acquire.
My current team is Cloud, Sephiroth, Fran, Vivi, and Garnet.Post too long. Click here to view the full text.
