Marcus Estrada writes: "It's weird to look back at gaming's history and see how genres have ebbed and flowed in popularity. During the 90s it seemed like action/puzzle hybrids were the "in" thing. Although some games remained in Japan, such as Tetris Battle Gaiden, popular series such as Street Fighter got their own wildly popular offshoots like Puzzle Fighter. In these games two players would face off and try to clear their board of blocks, which would cause effects on the other player's screen. Heroes Never Lose: Professor Puzzler's Perplexing Ploy (or HNL: PPPP) is hoping to bring back that type of game."
