YMMV / Centipede (1998)

• Good Bad Bugs: In some releases, Arcade mode runs on the same engine as Adventure mode, just with the playfield and rules tweaked to mimic the original game. In some releases, there's a cheat mode. On releases where both things are true, it's possible to bring Adventure mode weapons into Arcade mode and completely screw up the game.
• Polished Port: The PC version had much smoother framerates and higher res visuals than the Playstation version, as well as significant quality of life features like a proper radar and a visible powerup timer. The later Dreamcast release improved the graphics further and added an entire additional world.
• Scrappy Mechanic: The save system in the console releases — each level keeps track of your score, your lives gained or lost, and your completion of sub-objectives like saving Wee people. However, the entire set of results is updated if and only if your score is higher. This means that "bad" runs where you lose a lot of lives can be difficult to overwrite, because your good run needs to make up for the points earned during all that dying.
