I'm trying to complete the game 100% and I have missed one card in dead city. Why wouldn't you allow people to revisit these areas? I realize this is a linear open world experience, repopulate the areas with bots and allow people to back track if needed to complete the task of collecting cards or just to grind to collect more money or w/e. Just my opinion, but I am certain others feel this way.... I've completed everything minus getting one card on the second dead city mission which is sooooo lame.. reopen these areas...I'll have to play through again... and this is my second play through.
