Back in the day, there was this downloadable service called Sega Channel, allowing me to download any Genesis game at a time. It predated the Xbox Live and PSN services, though a Japan-only SNES satellite service existed as well. Anyway, this introduced me to Gunstsr Heroes, Treasure's first game and still one of the best games in general after nearly 30 years.

It's amazing what you can do with a toy gun, some wired, and a set of special space stones. With this combination, you can't lose.
