Having been gaming for quite a few generations now, I've seen the industry evolve exponentially. One of the things I've seen go in and out of "style" is third party exclusivity.
Does it annoy the gamers though?
It didn't used to annoy me as much. It really started when Eidos got in Microsoft's pocket with Tomb Raider last gen. Then Resident Evil on 3DS when PSP was promised an RE game that never released. The reason for the annoyance was because of those being my two favorite series since they had been originally released and now, regardless that I had supported both series for over a decade, wouldn't get the full experience simply because I had PlayStation.
This isn't a thread about why 3rd party companies do this, its me asking you if you've ever been annoyed by the practice and what game or series it was that annoyed you the most.
