I've found just the words to describe my feelings on PC gaming and modding.
"You can, but why would you want to?"
I can, with the money I've spent on my 360 to buy (or upgrade a little in my case) a decent PC to run most modern games. But why would I want to, if the only games I care to play on my PC are MUMORPUGERS, designed to be played on shit-stains, that Chinese goldfarmers use in their crowded sweatshops and Heroes Of Might And Magic III (And Jon Van Canaghem is still the best game designer to ever live) released in 1999?
To be more professional (and for the sake of ranting, while being chronically bored)
1. A gaming PC doesn't cost the earth
But you HAVE to know, how to make a PC, where to get the parts etcetera. You can do this, but is this really worth all the hassle, just to play WoW and see two extra pixels in Generic Shooter 5?
2. A gaming PC isn't upgraded every year
It bloody is, if it breaks. Which PCs tend to do every other month. Most of the time, you can fix them yourself. Most of the time.
3. It doesn't take an IT genius to do
But it still takes time and money spent on research and (most of the times for a newbie) trial and error. Googling trough forums, riding trough town to get better deals and ordering from shady sites online is SO worth it, allright...
4. Software compatibility
Drivers, Direct X and particular games won't like your sound card/graphic card/case color. Need I say more?
5. Patches
You still have to download them and most PC-exlusives (like oh-so-precious RTSes) come half-finished anyway. I dare you play Gothic III unpatched. Better yet, I dare you to play Vampire The Masquarade without downloading 2 gigs of fan patches just to run the bloody thing properly.
6. Noise
One point I won't argue with, since it's actually true.
7. Crysis
And another one.
So there ya go.
