I have no issue with exclusivity deals, as long as it's a new IP or it's a situation where the game has no money to be made, and one of the big 3 steps in to foot the bill. I have an issue with it when the game is an established series and played by many gamers across platforms, and the sequel is sniped, thus cutting off large amounts of the fan base. I think that is a scummy practice both from the Big 3, and the dev that made the decision (that they thought it was best for the series, and its fan base).
That we find this kind of thing acceptable in the gaming industry, is kind of ridiculous. Another way to put my stance on this is this:
Let's say Bioshock came out on all platforms. It's this huge success. Everyone is waiting for the sequel. If Sony turned around and made the sequel exclusive to them (thus cutting off all the gamers that played it on a different platform), I think that would be scummy. If MS had made Bioschock an exclusive new IP right out of the gate (so the first game ONLY ever came out on 360), I wouldn't be as miffed, because only 360 owners would have ever played this new IP. It's not cutting out a bunch of people that are already invested in the series. I feel exclusive sequel sniping pretty much hurts gamers overall, and that's not good for this industry.
I also feel it's pretty lazy from the big 3, to compete on this level vs. investing in new IP, or investing in their own games or improving their hardware + software. Also, in these kind of deals no one on that platform gains anything. Someone that owns an X1 was always going to get Tomb Raider. They don't gain anything by this deal. It's all for the sake of moving console units (at the expense of gamers overall, and the series overall fan base). That is why it's a shitty move.
So, where does Nintendo fall in all of this? They funded Bayonetta 2 entirely. It has an established fanbase on other consoles, but Sega literally dropped it, basically. It wasn't profitable enough. Is Nintendo evil for picking it up? What about Devil's Third? Do you really think Nintendo was the first call?
At the end of the day, I think we need to take each situation individually for what it is. Did Titanfall NEED exclusivity to get made? It shouldn't have with EA backing it. Does Tomb Raider need it? That I don't know. Square Enix hasn't had many positive reports when it comes to finances.
On the other side however, I see the benefit of what Microsoft tends to do in flexing their money. It creates competition and it creates compelling reasons to buy their console. If they aren't going to become a psuedo EA and just buy up every development studio out there, then they have to pay for exclusive rights. Without it, they are limited in what they can produce to generate interest in their product.
I understand why it happens and I even agree with it. It doesn't mean I have to like it. I sort of look at it like this: Final Fantasy left Nintendo. It had an established fan base. It pissed people off. Yet, the internet was young and this rage never festered on a global scale. back then, FF leaving Nintendo's consoles entirely would have been like Zelda leaving it. It was huge.
I have no issues with console exclusivity contracts. What irks me is when consoles are shunned by pure choice. Not because you were paid, but because you just don't want to even bother with it.
For all the whining PS4 users may do over the Xbox One exclusivity stuff, the simple answer is to just buy an Xbox One. If you won't... well, too bad so sad. I don't have to LIKE that the Xbox One gets exclusivity even for a short period, but it's not like Sony doesn't play ball either. Destiny anyone? Sony just picks those fights here and there because they can't afford to go toe to toe with Microsoft. I like it. It creates console parity. Does it suck? Sure. Does it give me a reason to own more than one console? Yes.
