>>49195338Just beat SMTV, got the true ending after around 80hrs. You do need to grind in certain points in the game (it doesn't have to be a tedious grind tho, as there's plenty of secondary missions and semi-bosses that are challenging and help you level up at once) unless you cheese your way out and I believe this is unfunny.
Maybe if PLA offers a deep enough array of secondary missions and tasks other than research ones, grinding will feel more natural (i.e. you gotta retrieve an object in an area full of Graveler, so you battle, catch and document them while doing the missionP)
