Months before I heard about For the Queen, I made a game that looks alike, with prompt cards (based on The Beast, at the time). It had three acts, with different themes and prompts, getting the story crescendo.
You can get a beta there : https://www.gulix.fr/blog/2017/02/23/apres-laccident-beta-2/ (in french and in english)
It’s designed for Solo Play, and the manipulation of the deck is more complex than in a standard For The Queen game. I intend to get back to this game in the coming months, using some things I learned while playing/designing For The Queen and hacks.
What I can say is by getting different Ages / Acts / Seasons, the layout of the game on the table becomes more complex. If you assemble the deck right away (Act 1 on top of Act 2 on top of Act 3), you lose some mechanisms (putting the end in the middle of the deck for short play) or need to add some layer to deck constitution (draw X cards from each Act, then assemble your deck …).
Also, you may need some transition between Acts if their content is different. Especially if your Acts cards have different back. If not, it can be a hassle to assemble the cards by acts (you need to look at the front, and loose the surprise of the questions at the first game).
For the Queen is really an easy to play game, easy to explain, easy to launch game. Adding any level of complexity (Acts, Characters profiles, different endings …) takes you away from that “easy-going” feel of the game. But that can be intended !
