I only realized that Oblivion had os many great mods recently (had it on 360), so I ever got to play them. I really also just feel like I can't go back to Oblivion after Skyrim (outdated graphics compared to Skyrim, comparatively bad combat, although Oblivion was best game ever until Skyrim). I have looked up a few (apparently this one called Neherim is really good, but I'd advice against playing it until after a decent amount of time in oblivion

I am looking into getting Oblivion on the computer to play this, but am not sure I can play Oblivion after skyrim (I couldn't play Morrowind after Oblivion, that great game from my childhood).
That also reminds me. Does anyone remember how Morrowind could diverge in so many different ways, like how if you had high luck, you'd find the dead guy with the levitation spells? What a classic......Oh nostalgia.......
