So here's a contender for possibly the stupidest question on the forum, but the array of purchasing options at Steam for AMS2 is bewildering to me now. I cannot believe I'm reduced to appealing for help on a forum before even buying the game, but there it is. I've been sim racing for nearly 30 years and have a physics degree so maybe it's not me, but here's the list. I want to buy ALL CONTENT, every track, car, DLC, and future update, and initially the option which came up was a one-click all-content option for $125, but once in my cart Steam threw up a "duplicate content in cart" error (even though it was the only item in my cart at the time) and when I repeated the search I got the following list. I currently have no AMS2 content at all. Do I need to buy just the season pass, or the entire list, or the season pass and some version of the game like the ultimate edition, or something else? Thanks.
