Playable Parties

I've known of this game for a while know, and last week I had a lot of fun playing Germany To Save (I hope I didn't miswrite the name).

I was wondering, are there any other mods that allow you to play with parties besides SPD or DNVP? For example DDP, DVP, KPD or Zentrum?

I wanted to know if it would possible to see the multiple choices that were available at a time for those parties, with respect with Weimar's degradation and the Nazis' ascension.

Thank you
