While technically Resident Evil 6 is not a hard reset of the Resident Evil franchise, it is for all intents and purposes, a reboot. This is a game made to wipe the slate clean, set up new characters, and drastically shake up the gameplay. How did it do? Well, it sold over eight million copies, but got review scores going as low as 5 to 6 from some critics. It also is decried by a large majority of the Resident Evil fanbase.
This isn't to say the ideas Resident Evil 6 explored were bad on their own. It tried to incorporate ideas from Dark Souls, Max Payne, and the development team's own unique tweaks to the survival-shooter subgenre. The co-op mechanics were built heavily around replayability and crazy matchmaking meet ups.
Unfortunately, this also tied to an utterly absurd narrative, and some awfully prolonged final boss fights. Resident Evil 6 is effectively three games in one package, and as a result, the excess of one-off mechanics and confusing decisions left it a directionless mess overall.
It's hard to tell if Resident Evil 6 is just a case of an intriguing concept stuck to the wrong IP or a genuinely terrible game that only a niche audience would enjoy. Considering the other recent series flop Resident Evil: Operation Raccoon City, maybe it's best Capcom approach future multiplayer focused entries with greater caution.
The lesson here being, innovating for innovation's sake isn't what people want. They want innovation that grows and aids your product.
If you'd like to give it a try, it's running an average of $19.99 for PS3, Xbox 360, and PC.
