...one sacrifice for some really good gaming experience i suppose because while mobile phones can be convenient your phone or game may be laggy and the screen might be too small ultimately it is a matter of convenience and preference for the players while the developers think more of the practicality
Mobile gaming works, and it has gotten bit better lately with launches of AAA titles such cod-m/wzm/df but still experience and convenience is not comparable to that of pc/consoles.
Yeah they often stay at home just to use their PC, Im on the opposite side of this, as I prefer the mobile better since I am frequently outside of my home, sometimes its frustrating too like most app works better on PC than mobile but its fine for me I learn to adjust in anyway like using this forum. I am more into using my mobile than PC at all.
I also prefer mobile due to it's portability and with wide reach of Internet, this duo makes everything possible at palm of your hands.
