Replayability = having a real solid reason to play the game again besides just seeing everything you already saw again.
Mutiples ending increase replayability.
Infamous second son has a ~12 hour campaing(if you never played) but thanks to a second ending the playtrough goes up to 20+.
Uncharted franchise has multiplayer,the campaing last more than the order's and more importantly,you spent most of the time controlling Drake.The Cutscenes only happens during the loading times.There is no "just cutscenes" chapters.
This is almost like heavy rain and you know what is funny? heavy rain had multiple endings so it has more replayability than this.
doesn't matter how good the history is,it doesn't justify $60.
Replayability) A solid reason is called quality or enjoyment. If it's good then you have a solid reason to play it again, not boxes to tick or useless fluff to unlock. If you need that, then the game isn't good to begin with, i've already been over this and am repeating myself.
Your concept of replayability seems to be that of going through X-amount of boring hours to reach a different "reward" than before. The same mentality that leads to all the bad open world games we've been getting.
Yes I:SS has a second ending, but most of the second playthrough is the exact same as before. I can easily make the argument that you can finish once, and then google the different video and watch it (no more than 3-5 minutes).
Heavy Rain doesn't have more replayablity because Heavy rain has bad (or little) gameplay. There is no enjoyment in going through it again, and once again, you can simply youtube the different endings instead of putting yourself through the same interactive cutscenes again. The Order has great gunplay that is fun to re-experience.
@Ludicrous I don't care how they price MP-only games because i'm not interested in playing them to begin with, whether it's 60, 40 or 20 dollars.
