That does hinder one a bit, but it can be done! The phone I had prior to this was huge! Honestly it was maybe 3 inches across and double that tall. Rping on it was easy because it was more like a tiny tablet. But it died u.u So i have an S8 now. I did MMORPG rp for a good while. Its really hard going from paragraphs and pages to express your every thought to a tiny chat box with limited characters in which you can describe what your character literally looks like or is doing. Its limiting.
