Is Hideo Kojima involved in this?
If the answer is yes, then my answer to the OP's question is twice on action, seven times on stealth.
If the answer is no, then zero times on both; I won't be playing it.
EDIT: So Kojima ain't involved. Therefore I'm not interested. MGS without Kojima is just a game featuring some characters from a series I like.
No offense but that is really ignorant. Anyways Kojima IS involved in the game.
This is a quote from an article of him describing Rising " a next generation, modern MGS" from a "young generation." "This is why I've passed the full baton for the creative side to Matsuyama (Shigenobu Matsuyama, Rising's producer) and other staff."
The article went on to say " This, of course, would be fitting considering his role as executive producer ". He is still dealing with the game he just isn't...well how do I discribe it... well re-read the quote. He is just letting other take over and he is basically guiding them as executive producer.
