What's the best way to structure branching dialogue for a 2D RPG?

[Avery66]

I’ve been trying to implement a simple dialogue system for my 2D RPG, but I’m stuck on how to structure the branching logic cleanly. My current approach with nested if-else statements is already getting messy and hard to debug, and I’m worried it won’t scale for the amount of story I have planned.

I swapped nested ifs for a tiny data driven system: store conversations as JSON with speaker, text, and a list of next nodes plus a simple condition check. It sounds slow at first, but it kept the branching from spiraling.

A tiny finite state machine for each NPC helped keep their mood and options consistent, and you can swap in new branches without touching every function.

I built trees with nodes for lines, branches, and ends, and a separate evaluator for conditions. It felt strange at first, but it stopped the if hell from spreading.

We added a lightweight engine that reads a data file and caches what options are available, so the runtime is fast and writers can test branches quickly.

I drew a graph on a whiteboard, then coded a generator that spits out in-game data. After shipping a few tweaks, adding a new branch dropped from hours to minutes.

Question: do you maybe have too many condition types causing confusion, or is the real snag that the data model isn't solid yet?

Sometimes I get hung up on UI polish and drift to that, then I circle back to data shapes and how you serialize them.
