I just downloaded the PC version but there doesn't seem to be a way to play the campaign.

A campaign for PC version almost certainly exists, I know this because of screenshots, and because the 2 reviews for the PC version (gamespot and cheatcodecentral) mention nothing of there being no campaign. Though page 2 of the cheatcodecentral review is missing: http://www.cheatcc.com/pc/rev/marveltradingcardgamereview2.html#.UPdyKPJa25L (Is there a way to make it work?) Lastly there is 3rd a review of the game but it's by PC Gamer. I could ask if anyone here has the mag with the review in it. According to metacritic, the review is from Nov 2007, p.76. Lastly here is the gamrankings page, but the same 3 reviews are shown: http://www.gamerankings.com/pc/932926-marvel-trading-card-game/index.html

I'm guessing that the campaign requires making an online account (which is no longer possible since online is shut down) but can anyone who played it confirm this for me? I'd rather not make assumptions.

Below is a screenshot of a campaign cutscene, which is clearly not PSP or DS version.
