PC Gaming is probably better than console gaming (please don't kill me if you disagree) and it certainly trumps mobile gaming. I feel like mobile gaming will never be able to compete with consoles or PC in terms of quality games, although you never know what might happen. At the moment though, I think mobile gaming is made to capitalize on the so called casual gamer market and that's what's really bugging me. My girlfriend really loves playing games on her phone, but stays away from the actually controller like it's cooties.
This question has been asked many times. I prefer mobile gaming but to be sincere, some games are better played on the PC.
Phones are more portable than a PC, and therefore, you can access them and play your favourite games anywhere, any time.
