I've played Oblivion since the game came out but I've never played any of the expansion packs other than Mehrunes Razor one. I've always wanted to get the Shivering Isles, so for 30 bucks, do you think it would be worth it to get the 5th Anniversary Edition which comes with Shivering Isles and KOTN, the map of Cyrodiil and the Shivering Isles, the steel case and the making of DVD for Oblivion? Also, I'm talking about getting this for the 360, not the PC.

I think the Deluxe version is for sale on steam for like 20 bucks or something, at least thats what I bought it for.

Last time I installed Steam on my laptop, it manged to crash it and it overheated constantly and I had to send it out to get repaired. I'm looking towards this for the xbox 360, for which I already own Oblivion.
