If it’s all episodes then the correct game title on SG is "All Episodes (Episodes 1-4)". Yes, the title doesn't include "Adam Wolfe" in it, because it's how the whole thing is called on the Steam store page...
All episodes give you three times more CV than just the first one. Also there are probably some people who want the full game, but have this thing (only the first episode) on their hidden list.

Thanks! =)
