I enjoyed Elder Scrolls IV: Oblivion. At least until my incredible vampire powers could no longer keep up with the enemy characters. The scaling enemies in the game rapidly become invincible if you spread your skill points to thin. I never finished the game, maybe I'll go back to it someday.
Or maybe I'll just move onto the next installment, Elder Scrolls V, a game which had its existence confirmed by the the announcement of the new Elder Scrolls book, The Infernal City.
The cover art is great to boot.
The Infernal City is due at the end of the month, and I'll post a review here once I've read it.
