Don't get me wrong. If I could I would, I just can't for lots of reasons that I'm too lazy to address. Anyways, guess I'll talk about em. 
 
My computer is pretty bad when it comes to gaming, especially if I want objects to be distinguishable as actual things. I can't really play any of the new games from this generation. Recently, I played the Half-Life games.  
 
HL1: Ran perfectly. No issues at all. :) 
HL2: Had to turn literally everything down but the volume for it to run well. On medium quality it ran at like 17FPS, which isn't very fun.  
 
So, there, my first reason is I have a bad computer for playing games on. So, why don't I just buy a new computer? Because I don't have sufficient funds to spend on something that is going to be outdated in a year, and upgrading certain aspects of a computer can be tedious and quite frankly confusing. 
 
Also, and probably my main point for writing all this, I don't think I can handle the power a PC gives you in gaming. This is mainly things like the console and modding. 
 
If I had a decent gaming PC, I would definitely be cheating ALL THE TIME. Its too easy to pull up the console and type "god" and have unlimited health, or ammo, or whatever. I know it would ruin the experience for me, but I can't help it if its there the whole time ready for me to cheat with. I played through most of HL1 without cheats, until I realized I could cheat and then proceeded to noclip to beat the last boss. Luckilly, HL2 doesn't have a console, or at least one that comes up when I push the ~ button. But Oblivion did and I played it for maybe 30 minutes before giving myself every spell in the game and trying to murder the shit out of Uriel Septim in the sewer. Then I stopped playing altogether and got it on console later to play through without cheating. 
 
So that's basically  why I'm not a PC gamer. 
 
The tilde key is bad news bears for me, but what about you guys? Do you fight the urge, or cheat your way through games like me?
