I use to be a PC gamer. I even played Morrowind on my old PC. The decision is very easy for me and only comes with age and the ability to look back on technology. When I built my first PC, the operating system I would use was a major concern. Did I want some flavor of Unix, Windows, or Mac OS? To help me decide, I went to the store. The shelves were filled with software for IBM clones. Mac had a section devoted to it. But in those days, there was very little. I left decided on Windows. The same logic I applied to purchasing Skyrim. Do I want it for the PC or for the console? Once again, I went to the store. Almost every title available for the PC is available on the console. Not only that, there seem to be fewer new titles for the PC. So, I bought for the console. PC gaming is on it's way out. PCs are being viewed more and more as productivity tools and less as gaming platforms. Desktops are also being replaced by smaller more portable computing devices (ie: Ipad). Disagree all you want. The writing is on the wall.
You'll praise the advantage of being able to load mods for the PC. Good. You do that. Have fun making them work too. At least DLCs, to some extent, are guaranteed to work. And software designed for consoles are "more stable" due to standardized hardware schemes. There are few variations to account for during development. PC development is a whole different beast. They have to make stuff work on as much popular hardware as possible. That creates plenty of room for problems.
Consoles may not be perfect. They may not be able to use User Generated content. But, they encounter less problems -- generally speaking.
You're wrong on SO many levels.
The reason you don't see PC titles on the shelves is because PC has moved a generation above consoles not just in hardware, but distribution.
PC has moved on to digital distribution for games, AKA STEAM ( Look it up, over 4.5 million users online at peak times every day ).
Again, you're one of the prime examples of common misconceptions of console gamers.
Please educate yourself and do some research on platforms instead of making decisions based on what you see in the stores. Realize that technology has moved up and the internet is used now.
