Which false twins do you know of that are regularly twinned but you feel shouldn't be?
Jasper & Zot
Plants vs Zombies
At first glance the comparison seems obvious, but the games are actually quite different.
Plants vs Zombies is a sort of tower defense game where you set up a variety of turrets to wear down incoming zombies, killing them one at a time before they reach your back row.
Jasper and Zot is more like Galaga in that you have a wizard moving back and forth along the bottom edge of the board shooting spells that transform the zombies into clumps of flowers. Then, similar to Puyo-Pop, you're trying to chain together large clumps of flowers for points. All the while you must protect your pumpkins, like in Missile Command.
