You have a lot of good choices. I have twd, tspp, lotr, IM and sopranos currently...love them all. I've owned xmen, rbion, acdc and avengers, liked them a lot too. No bad choices in that list in my book.you need to play them. Go with a theme you like.
Personally, I'd get rid of that ss and wh20 and get two stern games. Ss is a good game, just too shallow and easy...at least to beat the stiff o meter...not to complete the web, that's tough.
