I started gaming on the PC, but switched to the consoles (PS3) for the last 7 years, while I enjoyed it a lot thanks to great exclusives and overall a good system. The whole experience felt empty in a lot of places compared to PC gaming, so I decided to switch back to PC this time around. After switching, this is my 2nd year and I can honestly say, I don't wanna go back to consoles anymore.
Here are my reasons why I love PC Gaming:
1: It's cheap! Yes, the entry cost of PC gaming is more expensive than consoles, but...just within a year, I saved up to the console cost thanks to ridiculously cheap games. Why it is cheap? PC is more open market, you don't have Sony or Microsoft lock down and control revenue to satisfy themselves and their partners. On PC you have Steam, Greenmangaming, GOG, Amazon, and plenty of others all fighting for your cash. This heated competition further brings down the cost.
2: Long term investment: Forgets backwards compatibility, once you buy a game on the PC, you have the safety of knowing that anytime down the line you can access your favorite games. You don't need to buy 'remasters' to do so.
3: Speaking of Remasters, it is always awesome to play your old games with higher fidelity later on because you will have a more powerful hardware and/or modders will continuously enhance the game from technical perspective.
4: Mods: Yea I have to say it, mods only greatly extend the gameplay for practically unlimited time, but many tend to fix issues with the core game which many developers neglect.
5: More than just Gaming: With PC, you can do far more than just gaming. I not only do my work on PC, but with stuff like XBMC, I turned my PC into a multimedia powerhouse where I can watch TV shows, movies, listen to radio, music, etc. Right over here the value of your investment is completely justified in my opinion.
6: New kinds of experiences: PC is a constantly evolving platform which makes it the forefront of technological innovations in performance and gameplay. Thanks to the open nature of PC, developers don't need to take much risk if any to try out new types of games. With console manufacturers out of the equation, the connection between the gamers and developers is a much more intimate.
7: You decide where PC Gaming should go: There is no appointed company which decides what will be next for PC Gaming, it is up to you and your fellow PC gamers to decide where it should go next.
8: IQ: You will gain a lot of valuable technical knowledge of computers in general, surely would help you impress your girl friend!
