I am Nintendo fan and If someone asked me whats single 3rd party game that you want most to see on Switch, answer would easily be Dark Souls.
I am so happy because Darks Souls is coming on Nintendo platform, especially because full handheld mode in Switch, I will definitely buy every single Dark Souls game that might come on Switch.
Also talking about Nintendo fans that didnt played before Dark Souls, before I played Dark Souls for me best IP was easily Legend of Zelda, but after I played Dark Souls, DS very fast become for me best IP along side Zelda.
So, if you love Zelda you will probably like Dark Souls also. :)
Also I could said, if you love Dark Souls you will probably like Zelda also. :)
