Yes, of course he was. Strange since the latest main entry happens to be the best selling in the series.
SSM has two options. Do a drastic thing, and take a different approach to the next God of War entry. It'll take you 2 to 3 years to finally get it out of the door, and you'll do it a time when Sony will be preparing for the PS4. Sure, you might get critical acclaim, it might feel fresh, but you're taking a big risk and you'll be getting lost in the next generation shuffle.
Alternatively, you have your engine ready, and you can provide another solid entry in the God of War franchise. While it may not be revolutionary or drastically different, it gives you a little chance to experiment with multiplayer, but provide another good single player experience for God of War fans. The project won't cost that money either and will give you more time to think about the future of the franchise to ensure you don't mess it up. Fans will likely enjoy the game, you'll make plenty of money since it's bound to be a good success, and you still have the opportunity available to re-invent God of War on the PS4.
If it was me, I would fire the person responsible for going the first route in this case. It's much smarter to go the second route.
The reason why I basicalled laughed off Platinum is because it's a tired old thing people repeat. Yeah, they make good games, but do you know how much Platinums games sell in comparison to God of War? It's not even worth discussing. They are basically bombas in comparison since they sell less than even stuff like Resistance. What did Bayonetta sell? 1 million? What did Vanquish sell? Not even that. God of War 3 sold over 5 million. Platinums most successful game is seemingly going to end up being Metal Gear Rising, the game which is part of one of the biggest franchises in gaming. And even that will likely not touch the likes of God of War.
Which IP have Platinum created that is extremely successful? They haven't.
There is a lot more that goes into God of War than just combat. It's the presentation, the ridiculous aesthetics, combined with the combat and setting. Platinum probably couldn't pull off half of what SSM do with the PS3. Why would any business risk their franchise in that manner? When the God of War fanbase, the ones who go out there and buy millions of copies, expect that as a standard?
SSM can re-invent God of War themselves when the time is right. And the time for that certainly isn't 6 months before the launch of the PS4.
