Hey duders. I don't feel like writing a essay about it, but after playing Dark Souls II for a while, there's just no denying that Dark Souls I is the better game. It simply feels better in every single way. The one thing I would give DSII over DSI is the cloth physics.
Other than that there's nothing. The story, graphics, combat, online features, setting, atmosphere and emotion that you find in Dark Souls is just so much better than that of Dark Souls II.
