Battle Quest is a simple duneon crawler and is in no way an RPG. It uses some simmilar, but not the same, elements as in Warhammer Quest. But lacks the depth of combat. In fact the combat feels more akin to Tunnels & Trolls. but without even that systems depth.
That said it is a viable little solo game that does not require a map even. I think that with a little more fleshing out it has potential. But if you want a relatively light no-board crawler then give it a whirl.
