If Sony keeps the shovelware out of their launch lineup, and it looks overall solid even with less than 20 titles, they could come out of this looking pretty good with their attractive price point.
But their motion tech will not work as well as this... and their games need to be specifically tailored to those limitations well. I expect movement tracking and at least some standing experiences... but if they fell like relatively "full games", they should do very well for themselves.
Even Sports Champions had unlockables and a full campaign path... I played that game as much as any other AAA game I ever owned. Plug that into VR and I'll be quite happy.
They have a couple of games in that lineup that at the very least feel a little more than tech demos. Hopefully delaying into October means they launch with some substantial stuff.
BTW troubleshooting VR issues on a PC seems like the most infuriating thing.
