In an age where hack-and-slash style action games like Devil May Cry, God of War and Ninja Gaiden have all but been forgotten, the industry needs more games that require quick, twitch-like reflexes and fast-paced action. Metal Gear Rising was easily one of the best of this now near-dead genre.
Its entertaining story, fast-paced action, great boss battles and driving heavy metal music made for a fantastic treat for fans of the genre. What's more, Raiden's second time as a lead protagonist (redeeming himself after his iconic bait and switch with Solid Snake in MGS 2) made for a surprisingly deep story that delves into themes of power, strength, and weakness. Ultimately, it's a story just as rich and interesting as any other game in the series... and you get to fight a robot dog that becomes your BFF, so that's rad.
On top of all that, Metal Gear Rising: Revengeance is a game that manages to balance its interesting themes with copious, over-the-top 90s anime violence. In an age where the only "hack-and-slash games" simply seem to ape the Dynasty Warriors style -- or make themselves in the mold of more difficult games about tedious tactics and slowly waiting to attack your cheap opponent (cough... Dark Souls... cough), we need more games like Revengence to make a come back.
