I put on hold playing alien isolation.
I am waiting for 2 things before playing that cool game:
1) captoglove get fully integrated in steamvr , so like you said, we can use hands and not regular controllers . We can use captogloves now already in alien , but you would have to imagine as u are replacing keyboard and mouse with finger gestures, so at the moment , it does not work same as using hands in the real sense of the term.
2) use a "walk in place" method for locomotion in the game or katwalk mini (which in the end I ordered, but that I will receive in September)
So I feel what you are saying and your wishes
