While you can download stuff from Act 2 in any sequence you want to, I would not do so! All of Act 2 is an art experiment (if you want to be nice about it) or something an addled mind cooked up (if you are less nice about it). All Act 2 parts are not a game in any coventional sense, but art experiment at best or mental breakdown (would be fitting since it is mainly about the Son, which is on the way towards a psychotic character in DF 1 already).act 2 which need to download first?
So you can try Act 2 if you want, but no longtime thread visitor, be it fan or critic of DF, tries out this LSD trip on renpy!!
