The biggest issue that I can think of when it comes to the drawbacks of PC gaming has to do with the cost associated with it.

I had a poor computer for several years and I recently replaced it with a computer that has near top specifications for this generation. All in all, it probably cost about $1500 in parts to put together with several hundred additional dollars going into peripheral devices like monitors and so on.

The initial cost associated with it is much higher than buying an Xbox 360 or something like that.
