Why not just make the entire game exclusive at this point?
Marvel's Avengers

Sony has announced some additional "PlayStation advantages" to buying Marvel's Avengers on the PlayStation platform. These "advantages" are on top of the fact that only the PlayStation platform will have access to Spider-Man as a playable hero. These are also in addition to the exclusive beta period for PlayStation owners, the first of which begins on August 7.

These "advantages" on the PlayStation platform now extend to specific Community Challenges. These are challenges that will have different rewards tied to them. Community Challenges will be on all platforms but, as stated, there will be some additional ones that are exclusive to the PlayStation platform.

That's not too bad of an exclusive, but there is more.

PlayStation players will have 30-day exclusive access to a Legendary Outfit, Legendary Emote, Epic Takedown, and a nameplate for each Super Hero as they are released. This also holds true for each of the six heroes that will be available at the game's launch. While there will be other Legendary and Epic content to unlock, there will still be at least one of the previously mentioned items that is exclusive for 30 days before they hit other platforms.

Then on top of all of that, there will be special reward bonuses given to each Super Hero that is added after launch. All PS Plus subscribers will get a free bundle that contains a Rare Outfit, nameplate, and 100 free Credits. This is for each of the DLC characters coming out, including Hawkeye. These DLC characters are said to be free post-launch content. At launch there will be a free bundle for Ms. Marvel available for PS Plus subs.

Many fans and hopeful fans on other, non-PlayStation platforms have been growing a bit irate at the news over the past couple of days. Some have even wondered why this game just did not go full exclusive to the PlayStation platform with how much exclusive content Square Enix and Sony have put together for Marvel's Avengers. Of course, I am personally of the belief that timed exclusives of any sort is a shitty business practice that needs to die.
