Really, this is not something I care about, but I appreciate the effort and the time you took and can see how other people will appreciate it. I +1 sir.

Thank you!
It's just that I am really fond of artworks (there's some unique feeling to watching such images) and I thought there may be others who also like browsing through them, so why not share this info with them.

I enjoy looking at the artworks. Thanks for the list.

Updated with today's release.

Thanks for the list, I love artworks and concept art.
I can spend hours on the net trying to find just a little piece of artwork from a game I like.
