Is it a good idea to play other Elder Scrolls before I play Skyrim?

Is it a big long story like assassin's creed where to really grasp the story it's better to have started from the first-ish game?Is it a good idea to play other Elder Scrolls before I play Skyrim?
No not all. Every Elder Scrolls has had its own theme, diverse world, and original characters. Kind of like the Fallout seties, you dont use the same chatacter throughout the games (in Fallout 3 your actually born at the beginning of the game).

Without spoiling Skyrim too much I will tell you that The Elder Dcrolls IV Oblivion is merely a footnote in Skyrim. The characters will mention a few events that happened in Oblivion but nothing that you'll really need to know much about.

Go ahead and purchase whichever game you feel like playing first. I will say that Oblivion has no trophies and Skyrim does so that's something that might make a difference in your purchase.

Also if you're going to purchase oblivion make sure to get either the game of the year edition or the 5h anniversary version which include all the extras you'll want to have.Is it a good idea to play other Elder Scrolls before I play Skyrim?
