Joe Gloria is a freelance concept artist who most recently worked on Assassin's Creed IV. You won't find any art from that game here - most of it is still under lock and key since it's not out yet - but you will find some awesome fighter jets, future cities and fantasy landscapes.
My favourite? The RPG tribute up top. Who knows, if we're lucky maybe one day a Western developer will take a page out of Okami's book and do something that actually looks that cool.
