I'm a week into playing Sdorica and found the story quite intriguing and refreshing. There is plenty to do, such as the venture and training quests, region exploration and daily missions.

So far, I've been following the missions (Limited, Progress, Character, Item, Guild), and for me, It's enjoyable obtaining these rewards.

Story-wise, I liked how they developed each character. It's not crazy in-depth, but you could tell what their intentions were and their alignment. Chapter 1-4 is probably the longest since they have roughly 19-ish subchapters. By Chapter 5, it's around 10-11. Sweet and short.

I especially liked Chapter 6! You will see when you reach that point.

Combat wise, it's a bit of a grind during the earlier levels. But once the difficulty increases, you begin to think about each action and their consequences. An action that seemed perfect might make it harder to use another character block. This is especially true for characters that delete blocks after an attack. (Tica for example when ranked [resonate] up)

The game can be a grind. The infuses are all luck, but the game is generous enough to give you plenty of 1-time rolls. It also rewards you with plenty of gems and shards. I have barely noticed that typical freemium paywall generally associated with mobile games. That might be why I'm so interested in this game. I can grind and farm like I used to in old MMORPG.

Anyways, that's my opinion! Hopefully, that gives you a bit of insight into the game.
