Probably because Alyx is more of a 'actual' game than something like Beat Saber that's essentially Guitar Hero but for VR and more of a 'novel/toy' game. VR as a platform just isn't really have a lot of staying power or real interest for a lot devs at the moment but hopefully with the debut of Alyx more people will look at VR differently and think "Hey, that was actually dope. Can I have more of this please?"
