Let's Compare - Parodius

[TrekMD]

The Parodius series is a series of horizontally scrolling shooters developed by Konami. The games are tongue-in-cheek parodies of Gradius, hence the name (Parodius is a portmanteau of Parody and Gradius). It also parodies many other Konami franchises, including Antarctic Adventure, Castlevania, Xexex, Axelay, Thunder Cross, Taisen Puzzle-Dama, Space Manbow, Ganbare Goemon, Lethal Enforcers, Tokimeki Memorial and TwinBee.
