"We need to be honest with ourselves. If you’re considering picking up Kingdom Hearts 2.5 HD Remix, there’s a 75% chance you’re doing it for Kingdom Hearts: Birth By Sleep. There is absolutely nothing wrong with that. In my opinion, Birth By Sleep is the best and most important installment since Kingdom Hearts II, and while it was nice to have it as a PSP exclusive, it was also a heartbreaking decision for everyone who loved the series and didn’t have that system. In my mind, Kingdom Hearts 2.5 HD Remix is the means of rectifying that and giving everyone the opportunity to play a game they deserve.
Mind, that isn’t the only reason to get Kingdom Hearts 2.5 HD Remix. There are others too. It’s pretty, for one. You can’t deny curb appeal, especially since those Square Enix PS2 games clean up nicely. More important is that the variations of Kingdom Hearts II and Birth By Sleep appearing within the compilation are the more robust, Final Mixes, offering additional content to enjoy. I suppose completionists will also be pleased to have a retelling of Re:coded that doesn’t involve playing through that cash-in of a spin-off, but everyone else can go on pretending that installment never happened."
