Pokemon Pinball is exactly what you would think. It's a pinball game that has a Pokemon theme. Yet that's not what makes this game great it's the fact they Nintendo made it feel like a Pokemon game by adding the concept of traveling from town to town and collecting Pokemon along the way. Not to mention the Rumble feature which was a new thing at the time.
Was a awesome update to the Red/ Blue versions in how it brought Jessie and James Team Rocket from the anime and brought them into the game. Also who didn't love how Pikachu would follow you around and tell you how he felt?
