Wish I never saw this thread... I could have gone out to get dinner, get some beers, could have put money away for home expenses... But now I have more Steam VR games (some that I'm too embarrassed to even name.) They were on sale!!
I am considering Titans of Space, but still undecided.
It's very cool if you like astronomy, but it's relatively short. I'd never really 'got' the scale of some of the giant stars until I saw them in VR.
The motion controllers don't make a huge difference, though the interface is clearly designed for them; the main thing I remember is being able to 'grab' planets and hold them in front of your face for a close look.
Only thing I picked up was No Limits 2, as the other games I'd have bought I either owned or they didn't have much of a discount. I'm not paying $20 for a wave shooter again.
