This one was a follow-up question to the asker wondering whether Blood & Laurels was still available anywhere. (It isn’t.)
If there are any other games (IF or otherwise) that you’d recommend for deeper conversational experiences, I’d love to hear about those… I have a rather broad set of interests there, so anything you find especially exciting, new or odd would be great to hear about, especially where conversation is at the center of the game.
…right, okay. Well, that’s quite a broad field, but here are some possibilities, preferring more recent games (though interesting conversation games go back for quite a while).
Parser-based conversation games are often designed to let the player explore concepts that interest them, treating the non-player character like a big encyclopedia rather than a goal-oriented partner in dialogue. That tradition goes back — well, back to the 80s, really, since Infocom’s murder mysteries allowed you to ask characters about important subjects and clues.
A few more recent examples that are either carry some of this concept over to a different interface or allow a different spin on it:
Subsurface Circular (above) and Quarantine Circular are both primarily conversation games. Subsurface Circular has some embedded puzzles in the dialogue, including puzzles around manipulating emotional states and the knowledge of both the PC and other characters. As you find out new things, you gain “focus points”, an inventory of topics that you can introduce into conversation.
Speaking of manipulating emotional states, that’s really the primary approach in The Red Strings Club: you mix drinks for NPCs to affect their emotional status, then ask dialogue-tree questions.
