Battletoads is one of the most controversy-causing NES games there is. Arguments are tossed back-and-forth, one side saying that the game is good, the other saying that it isn't. Why the controversy?
The problem many gamers have with Battletoads is the extraordinary challenge. This is mostly caused by a great number of obstacle courses without enough brawling levels. There are so many gamers that can't even get past the third level of this game, the speed biking level! This causes those that have trouble in the game to degrade it, and others to rate it rather highly.
