Its just comes down to your preference and your use case.
I hope you are not planning to play in public, that too on a tablet.
Most people play on PC, cause most people "Play" the game, its made for pc and to be enjoyed best on that platform.
But I can imagine people may need to resort to phone, but getting android port is hard for unpopular games, and the wait for update is hell.
But yes if there is no option, you can always turn to Joiplay with renpy plugins, and you dont need anything more that a mid range android to play VNs seamlessly
no,
use my phone for work with too many work apps on my phone
pron and games stay strickly on a personal laptop & table that aree never synced to the cell
Never use mobile phone/iPad for gaming or any kind of pron as I use it professionally. I don't use any device used for work to view or otherwise play anything of a questionable nature. If I did, I'd get a cheep Android tablet and encrypt it... but probably never will. I love regular ol' games so don't get the urge anyway.
I use my Android pad and not my phone anymore due to the size difference. I've never had a desktop PC. Maybe a laptop one day but my pad works just fine. I don't play any real interactive games needing a mouse. But that could change.
