That might be quite difficult sorry. The only non Nintendo platforms I've ever fully owned myself are the PSP, Xbox 360, Mobile and PC. I did try and include games on those platforms were I could on my last list but ultimately very few of my favourite games are on there.
It at least will be a true genuine list of the top 50 games I've ever played. I'm not trying to be intentionally deceitful to skew results a certain way. I'm just a unique type of gamer. I've gotten into quite a few third party games this year though (albeit on Switch), so maybe that will help keep things at least varied publisher wise.
That's... totally not what I meant to say. There's no problem with your list being your genuine 50 favorite games, in fact that's how it should be. OTBWY's list itself wasn't all Nintendo, anyway. I meant as in, don't be a bum and spoil your list early for everyone.
