Anyway to be serious it's a first person dungeon crawler and you draw a map of the dungeon you're in which has multiple floors.
You mark walls, floors, doors, FOE patterns

, chests, shortcuts, puzzles etc.
You have a party of 5 where formation matters, people with guns and bows go in the back row for example.
PQ is a decent starting point to figure out if you like the genre but the biggest criticism is the characterisations. It relies on you knowing the cast of P3 and P4 but they really bastardise their portrayals down to a single trait which really does the characters a disservice.
