Why not? If it was titled "Kingdom Hearts 3" then heck ya, people would notice it especially with all the promotion going on here.
To be honest, I wish BBS was called Kingdom Hearts 3: Birth By Sleep. I know chronologically the title wouldn't make sense... but it just disgusts me everytime someone claims BBS to be a useless side game. And I had this really bad argument with another youtube user and said "Square Enix is being so lazy, bring KH3 on! Stop with the useless side games!"
1. The KH team is busy on FFXIII Versus, they CAN'T work on KH3 -_-
2. They have been developing 3 KINGDOM HEARTS GAMES AT THE SAME TIME. One of which was a bridge game (Coded), one of which was a side game (358/2 Days), and one of which was a MAIN GAME (BBS) I'd hardly call working on 3 titles at the same time to be "lazy"
3. Why is he assuming BBS is a "useless side-game"? Is he stupid?! That's like saying "Oh Kingdom Hearts 2 was useless filler, they should've just given us Kingdom Hearts 3 instead of Kingdom Hearts 2!"
...Yeah, I'm never gonna let that go.
