I have played many really good games such as: Gmod, Elder Scrolls,Metro and the S.T.A.L.K.E.R Series. Also Fallout also one of my favorite but currently I like Dark Souls just that bit more.
However the best game series I have ever played are the "Souls Games", like Demon Souls, Dark Souls and of course Dark Souls II. The reason I enjoy the Souls games so much is that is so HARD!That you rip out your hair and stab yourself with a pencil (if there is one around but you can improvise). The whole lore of it which is Dark Fantasy one of my favorite genres, say's about the Undead which you are one of them, where as they lose hope you "Hollow." Which is a form of insanity and you lose all will to live and just in a nutshell brain dead. This is so great that is hard because when you rage quit or lose hope it's like being the actual character and it's immersive in that sense that you feel just like your character. Furthermore, when you beat a boss itttttttttttttttttttts so good that you just want to thank your parents and that malarkey because you are so happy lol. Before I get carried away too much here are some pictures.
