I've begun playing the phone game Terra Battle.
It is produced by Mistwalker Studios. A studio founded by the creator of Final Fantasy himself.
These are the same people who made The Last Story. Which was a fantastic RPG imo.
For a mobile game, it's pretty fun. It's essentially a turn based RPG puzzle game.
It has a lot of text based story/lore.
There are frustrating bits but I think that's because I haven't figured out all the mechanics yet.
It has tons of content. I've been playing for 5 hours and only gotten to chapter 5. It has over 60 IIRC. That isn't because I struggle either. I'm doing nearly every stage on the first try. There is some grinding in those 5 hours, but I'd say it was only 1 hour total of the time. Then I steam-rolled everything for a while and now I'm coasting.
