10 Video Games That Were MASSIVE Jokes

10. Frog Fractions

Anyone going into Frog Fractions hoping to learn anything vaguely mathematical - or herpetological, for that matter - is going to come away disappointed by half.

The only common denominator between Jim Crawford's ineffable amphibian arithmetic 'em-up and its prosaic classroom equivalents is that it's of virtually zero educational value. What begins as run-of-the-mill browser teaching software about a frog and his sums soon devolves into a surreal, Dadaist journey through every genre imaginable. There's a text adventure to guide a spaceship back from Bug Mars, a rhythm action segment as the hero frog Hop attempts to become president, and a business sim which sees you flogging bug porn (frogspawn?!) for profit.

Pretty much every video game convention you can think of is ridiculed in some way. There may be no fractions, but it's a wholly unforgettable - and indescribable - experience.
