I think I used it in Horizon Zero Dawn once just to test it out but not really my kind of thing.
Elite Dangerous is great. Has quite a nice photo mode too.
Yes I do and also fuck you, Flickr, for limiting my free account after such a collection I've uploaded into you already. Fuck off, Flickr.
What I did was just make another Flickr account with another email address, that's all you need. Another option that should potentially work well is using a regular art sharing site like Deviantart.com for example. You can upload traditional art as well as photography there, without limit, without image quality loss and you can hotlink images easily from there.
