Hello, this is my first post here, so I hope everything is ok:
Advantages of PCs
You can find a lot of games like in the Steam Origin store.
Most games (physical disk) are very expensive but a lot are cheap (in key stores).
It is easy to do more things at the same time.
Shooter good at playing with PC.
Disadvantages
Hardware can be quite expensive (& and difficult to change if you don't have any ideas how or you have a notbook).
Not every game were release for PC (damn Exclusives).
Without a gaming wheel maybe hard to play games like "NfS" or "Project CARS".
Consoles Advantage
Console exclusive games.
You can play every game with a steady FPS. (most games)
Mostly cheaper than a good PC.
Disadvantages
Your games don't have the highest graphic optimum.
Some games are a bit different from their PC buddies.
