Heard this is one of the best DLC's Bethesda has ever put into a game of theirs...how wrong would I be to not play this if I enjoy oblivion? is it a must?

been having issues getting shivering isles to work even though I have it, haven't been able to get it patched right, thought I did and was saving it for the end of my play through only to realize near the end it wasn't activated and I couldn't play it.

whats the general opinion here

I think the general opinion here would be to most definitely absolutely play it without any hesitation whatsoever!!!!!!

Or something like that

You′re saying you′re having difficulties getting it to start? Have you ticked the correct box and waited 24 hours in-game?

I have, if you want to see what I have going on I have a very detailed description in the hardware issues section of the oblivion forum...

definitely did that though

I've never played it. But I've heard others say it's pretty good.

There was a point in time where I didn't return to Cyrodiil for at least 50 hours of consecutive gameplay.

I think this has a lot to do with the variety that the Shivering Isles has to offer.

I'd strongly recommend playing it. I'd put it up there with Tribunal, Point Lookout and Dawnguard.

Pointe lookout, I can't even remember that DLC...I think it was in a fallout game but don't remember specifically which game or what the setting was like...miss some fallout hope a new one gets announced soon
