Other than it being the start of a somewhat popular SRPG series, SN1 barely has anything going for it.
The Battle System is far from original although still passable. Everything hits super hard if you try to and level up your party evenly, until you throw all EXP into 1 or 2 characters then it turns into braindead easy mode.
Story is a shallow and typical "Save the world" scenario with one-note characters, but what makes it worse is how 80% of it is just beating the snot out of the same dudes over and over again which gets very tedious very quickly.
