What's your favorite original theme concept in pinball? As in theme/artwork only, not the quality of the actual gameplay.
Mine is Big Guns. The medieval sci-fi theme is so appealing to me (same as with BK2000), and the playfield is my favorite of Python's art. I love the theme integration of the castle walls in the upper playfield, and the tanks/cannons with the standup targets representing the treads is especially clever.
