I used to not be able to afford any consoles, so I was limited to an old PC and the Nintendo 64 we had at a friend's place. The N64 was always something special to me, because every time I got to play it it was like a special event. I would always play Donkey Kong 64 on it and I thought it was the greatest thing in the world. I know better now (fortunately), but DK64 still holds a special place in my heart.
Thanks to my lovely girlfriend who I live together with, we now own a Nintendo Switch, PlayStation 4 and XBox One, as well as two 3DS's and a regular DS. Among all of those, I'd say my favorite would have to be the Switch. With over 500 hours of active playtime in just Breath of the Wild, none of the other systems compare to the amount of content I have enjoyed on the Switch.
