When it comes right down to it, I have made some awful purchases for my PC gaming in 2011. Skyrim made all of those bad decisions melt away.
You have to play this game to understand why everyone is so happy. But, there is one thing that the PC version holds over the console version, not graphics or frame rates, no no, the MODS!
Skyrim Nexus is what makes Skyrim on PC so wonderful. Newly designed weapons, clothing, facial renders, environment boosters, New homes, caves, and areas to explore. Better built maps and user interfaces. Class upgrades ranging from looks to new magic you can use. So many possibilities and new mods pop up everyday.
So, if you have the PC to run this amazing game, buy it! and then go directly to Skyrim Nexus and pick your favorite mods. Becareful and be patient though when choosing, some mod makers put out different versions of the mod to compensate for glitches or clashes with other mods. I recommend you install the Nexus Mod Manager and the SKSR loader so you can get the best visual experience, the rest is up to you.
Have fun with this game, it will last you for years on the PC. So glad I bought this for PC.
