One of the best RPGs ever, after you add the Mods for Oblivion it becomes incredible
What I'm saying is Elder Scrolls is infamous for their mods. This game is an easy game to mod for a reason. Once you find mods that you like you'll have fun, period.
Get this game and mod it, it costs around $30 but I got it for around $7 at amazon.com used.
I'm going to tell you get some graphics mods, it looks like a completely different game because of how real the new graphics mods make it look. If you're worried about the story have no fear, the mods generally do not take away from the story mode but be careful of what you download since the mods can sometimes interfere with each other.
