I'm a huge fan of 60s culture, decor, and music, so a soundtrack for backers would be fantastic. Vinyl would also be amazing.
Not to be too demanding, but will the kickstarter offer only the PC version for backers or will console versions be offered as well? I'm primarily a console player and I see many kickstarters that only offer PC versions of their game to backers even though they confirmed they'd be bringing their game to consoles.
