I was introduced to The Elder Scrolls with The Elder Scrolls IV: Oblivion. Despite how much the game irritates me (falling down stairs instead of WALKING DOWN THEM!!!, and the combat), it's still a great fantasy RPG, and it's mod support and community is ridiculously amazing...aside from the imbalance of porn-mods to improvement-mods.
Anywho, Skyrim. I'm interested in it, and definitely considering getting it. With Fallout 3 being an improvement to Oblivion, I'm looking forward to Skyrim being a similar improvement to Oblivion. It seems with each new game, Bethesda gets the formula just a bit better than the previous.
So right now, I'm playing Oblivion. Not really because I'm breathlessly dangling from my cage attempting to hold on until Skyrim comes running up to me with trampoline-net and joyful tidings, but rather because I'm in the mood for a good fantasy RPG with ridiculously amazing mod-support and an imbalance of porn mods to good mods. I'm confident Skyrim will replace my Oblivion install however. I just hope they release the modding tools within mere days of Skyrim's release. Not doing so would be a sin against the gaming gods that have, to this point, blessed Bethesda and its modding-oriented player base.
