I'm looking forward to all aspects of 2.5. The games featured in the collection were my favorite in the series. KH2 and BBS also have a little extra special meaning to me. Kingdom Hearts II was the first KH game I ever played, and Birth By Sleep was the game I played that reintroduced me to the series and got me back into it early this spring.
Above all, I look forward to reliving my childhood, and finally getting to play the bonus content from the Final Mix. I have 2 cousins the same age as me, and we have next to nothing in common, but we shared a love of Kingdom Hearts for several years. My uncle even made us all Keyblades out of wood (there were a few errors, but we didn't notice them for a few years). We also all got silver Kingdom Key necklaces (though they all snapped in half, as they were cheaply made. As a result, I have bought us all new ones for Christmas). We constantly met up to play the games, and would call each other when we accomplished something we felt was major. After a few years, our love for the series began to fade, as we didn't have the handheld consoles at the time, and we began to grow apart a little bit. Since the announcement of Kingdom Hearts 3, we've all met up a few times to start replaying them, dusting off our old Playstation 2s. We've already beaten the original Kingdom Hearts together. 2.5 offers me the chance to strengthen my relationship with my cousins, and the opportunity to replay our all-time favorite video game. That's what I look forward to.
