I love TES, unreasonably. For that very reason, I don't think I'll be buying Skyrim right away...
1. I'm studying something that I find very difficult. I don't want to trash my life for this thing
2. I'd be really saaad if Skyrim was a big disappointment
Basically, I'll probably wait for patches, downloadable content, expansions and mods to come out before buying it.
I'll also have to buy a new computer to run it, and as I am not exactly swimming in money, waiting about a year or so will probably mean that a computer that can actually run Skyrim will be much more affordable.
But, yeah. I don't think there's any doubt that I will buy it
eventually.
