There's one game from 2011 that's going to get in my top 50.
Dark souls, every game session is a solid 10/10 so far. I have only just arrived in Anor Londo after 35 hours on my 2nd character. I'm taking it as slow as possible, letting it all soak in. The decent to Qualaag's domain was truly epic. Then I found a way even further down to Ash lake, just to get the hell out of there again. Did not look like I should be there yet at all.
