If someone have still doubts aside the easiest way (that is Buy this DLC and the full series on steam)
You CAN buy Choice of the Vampire: St. Louis, Unreal City on the other platforms, You just have to read to the end of the “Memphis” chapter in the FIRST Choice of the Vampire game here on the site (or from the Google app or Amazon Version), NOT from the Choice of Vampire - Memphis game (that is because the 2nd game page become officially obsolete for his “save character” function that ISN’T NEEDED anymore and if you already purchased “Memphis” in the past you will find his chapters already aviable in the first game )
I opened the post because without an official release info on the blog someone could have missed it and maybe like me want to buy only the last book instead of re-buy the full series on steam
I ask to the CoG staff if could be possible in the future to add a different new Bump image cover to the First Choice of the Vampire in the list of CoG games this for showcase there is a difference now from the past version (and that pratically it become like Choice of Romance - first released in 3 parts and now it could only be found on the site and elsewhere as 1 full pack game) also if is possible to allow purchase for all the chapters from the start page like it is in Choice of Romance this to make evident THAT contain ALL the official releases. Hope this is helpfull, Thanks for your attention
