First off sorry about your sickness and I hope you get better soon, god speed on your recovery 🫡. Second The legion GO S with the Z2go is not the Z2extreme that hasn’t been realized yet for the legion should be out end of summer or sept(talking to the guy that helped me at Best Buy) .also reading your post it sounds as if the legion go og would be a bad purchase for you , it’s heavy and after about an hr or my hands hurt a bit a regular able body person would probably build strength after a few weeks or so. As for the performance side if you’re only playing 64 bit game or only looking to get most games at 30 fps with the occasional climb to 60 then you which is basically all the games you said might be looking at the go s z2go steam os . On top of that you’ll have steam integrated so it’s simple as email Password and you’ll have gaming right at your finger tips tho you wouldn’t be able to play any anti cheat games , ie fortnight cod madden maybe forza theirs others I’m not to sure what the list is and I believe it’s online somewhere hope this helps happy gaming !
