Quartet

Quartet, a 1986 Sega System-16 arcade game and has the best soundtrack ever. The 2005 medley by the phenomenal Sega band [H.] is fucking glorious: [link] Anyway, I wish someone at Sega would remake it, updating the gameplay to modern specs and reinventing it a bit ala Elevator Action Deluxe/Spelunker HD.

For my probably-never-get-to-it ultimate Sega doujinshi, I have an entire script ready where the Quartet crew gets hired for a rescue operation where they clash with Alex Kidd who's now become a space pirate along with Phantasy Star characters and a million other Sega cameos. One day, I'll make it. Maybe when I'm fired and have time.
