This is semi-related. Videogames For Humans has playthrough transcripts alongside players’ commentary on the games. I remember I loved reading this book. An audio version of it (or a similar project) could scratch that itch.
This sounds really interesting, I’ve actually thought to myself the same question whilst playing games. Also, I kind of wanna make one of these but I’ve never done voice acting classes.
I hope you give it a go!
If you need feedback, advice or help, I’d be happy to support you (as I’m sure many others here would too).
I think nothing beats a real speaker. I made a test with ElevenLabs and the result was not very good, although it was quite al lot of work.
I have no idea what I’m doing either, but here’s a quick recording (about 14 minutes) of the first bit of Grand Island Bank Robbery - is that non-terrible enough that you’d listen to it?
It’s great! I definitely want to hear that! 
That’s probably just a small fraction of the whole game, isn’t it? Are you going to record the rest as well?
I certainly could, yeah. I’ve recorded read-alouds of books for family before; just pick away at it a little bit most days until it’s done…
Actually, this is disingenuous: we grew up reading books aloud, and I’ve done a little bit of recording read-alouds as gifts for family, so… this may all be in that video (I haven’t watched) but we’re a text-based medium:
- Character voices are a lot of work; you can just read as yourself. Some people even find them annoying, especially if they’re overdone. I did do a bit here but I didn’t think about it ahead of time and I didn’t try to be remotely consistent.
- But DO consider shifting voice a little for player input vs. game output, or narration vs. character dialogue. I’m leaving a little pause at the input prompts (and using a slightly higher pitch when I remember). Or just something like regular voice to telephone voice or whatever?
- Stay hydrated: you actually get more wet mouth noises when you’re too dry (making saliva to make up for the dryness?).
- Decide what you’re going to do to mark places that need edits so they’ll be visible in the waveform when you’re scrolling through the audio: a clap or a finger snap will make a sharp tall point that you should be able to see.
- Similarly, decide what you’re going to do when you mess up: leave it in, correct yourself and keep going? Or take a pause and start back a little bit so you can chop out the bad part later (remember to clap or snap, and remember to START at a place where there’s a little break so you’re not trying to line up the cut in mid-talking).
- Take your time: the “standard speed” for oratory speeches or dramatic readings has been 150 words per minute forever: that’s probably significantly slower than. Give the text space to breathe. I rushed this recording a bit: I was expecting it to be about 20 minutes, not 14. You could grab a piece of text that’s about 150 words long and try taking a minute to read it, see what that feels like.
There are probably some recording tips too but I should get to work pretty soon:
- I’m using Tenacity (fork of Audacity since they’ve decided it’s OK to add trackers).
- Clicking the volume scale after the mic icon to check the recording volume (want it to fill a bunch of the scale but not go into the yellow or red).
- Leave a bit of silence at the start before you start talking, for a “silence” sample for the noise reduction.
- Hit record (Shift+R) and go.
- Afterwards, select the silence at the start, go Effects > Noise Reduction > silence sample (or whatever it’s called), then Ctrl+A to select all, and do the actual noise reduction.
- Go through looking for my edit clicks and chopping out throat clearings or bad takes or whatever. Ideally I also listen through to the whole thing and I’ll chop out (or fill with silence?) over some mouth noises or whatever.
- Run Effects > Normalize on the whole thing to adjust the volume so the loudest parts are at a consistent level - it’s always annoying when you’re listening to something and it’s way louder or quieter than you expect.
- Export to MP3.
I’m sure actual audiophiles will have some beef with that but it’s simple and gets something that works well enough…
