That whole different audiences thing is touchy. I stand by that releasing too many games at once is not good. It will impact sales regardless. More options means less chance of buying for consumers regardless of genres
So long as the options are there. Some people will look twice.
You're not wrong, but the idea is that getting a smaller piece of a bigger market is potentially better than releasing in a dead season. As we all know, consumers have seasonal buying habits with games -- that is, they sell better at certain times of the year than others. With niche games, a developer has some leeway to release 'whenever', knowing it's niche will seek it out and buy it... but a lot of games simply have to bite the bullet and go up against the competition in a heavy release season because releasing in a dead season is just as much, if not more, risk.
Then there are basic financial concerns; your game may have taken 6 months longer than expected to get out the door, but that doesn't mean you can sit on it for 6 months while you're waiting for the right time to release. Your carefully crafted plans to release in March now have you releasing in, say, November. Besides, even if you plan for some 'dead' season, there's always the chance some other game can steal your thunder.
With something like Mad Max, I'm sure the release is tied in with the bluray release. Do they wish MGS was releasing some other time? Sure. But... ultimately I think I agree with others... MGS is selling to a very specific [if large] market, whereas Mad Max is the type of game people will just pick up because it's Mad Max and they liked the movie. If my wife were the type of person that randomly bought me games, she'd buy me Mad Max.
As it is, it's my birthday this week and I know it won't be under my birthday tree because she doesn't buy me games.
