Great Deals Tony !
I envision some CAGers will come down with the same syndrome I've currently had for the last year: Skyrim, aka gamer's crack.
I used to be like one of you, buy cheap games just for the sake of being cheap. Then I bought Skyrim........ CAG disease cured
SO YES, BUY SKYRIM AND ALL BESTHEDA GAMES NAOUGH!!! DEW IT!
I'll mention this...if you intend to try out some of the more recent mods (which you should), a lot of them require assets from both Dragonborn and Dawnguard (and sometimes even Hearthfire). I actually preffered Dawnguard over Dragonborn, but that is likely because I didn't find Solstheim as gratifying as others.
If you plan on using mods, then you NEED the DLC. It's amazing how many people I've come across that buy vanilla Skyrim so they can use mods, and then get peeved when they find out many of the great mods require the DLC. Why do they require DLC? Because the DLC adds cool modding assets for mod creators to use.
For example, I'm working on a mod, and after much deliberation with myself, I have decided to require Hearthfires DLC for my mod. The DLC does NOT prevent you from using any mod; but not having the DLC will prevent you.
