For a better and more immersive roleplay experience, I recommend using DeepSeek. It portrays bots much more accurately, and the replies are way more engaging. You can access my DeepSeek guide here. Find more DeepSeek tips below.

General Info

・・

ʏᴏᴜʀ ᴘᴇʀꜱᴏɴᴀ: Literally anyone or anything — any gender, race, faction, backstory, even animals, objects, or multiple characters. You can also be a canonical character or an original one. But you don't even have to originate from the Fallout universe.

If you don't want to start as strangers, make sure you specify your relation to MacCready (eg. friends, lovers, enemies) — either in your persona description or chat memory

ᴄʀᴇᴀᴛᴇ ʏᴏᴜʀ ꜱᴄᴇɴᴀʀɪᴏ: This bot is fully sandbox. All details are provided by you in your first message and chat memory. You can start anywhere. It doesn't have to be the Commonwealth. It doesn't even have to be the Fallout universe

・・

This bot is designed to keep permanent tokens minimal. MacCready’s personality and concise backstory are included—nothing else.
Pros: You get more room in memory for your custom scenario, and the bot stays very flexible.
Cons: Slightly less accurate to Fallout canon than my other basic bot—but the AI still has a solid grasp of Fallout lore, especially if you use DeepSeek.

ᴄᴜꜱᴛᴏᴍɪᴢᴇ ʏᴏᴜʀ ʟᴏʀᴇ: I’ve left out world-building details and kept tokens low to give you freedom to shape the lore as you like. This allows you to:

• Change or rewrite canon however you see fit (note: the AI defaults to canon-accurate assumptions for elements it knows, unless you "override" them)

• Use more tokens for the lore that matters to your story, without wasting memory on redundant info—your persona description or your chat summary suffices for this purpose

• Import (transplant) ongoing stories from other MacCready bots if their definitions are no longer entirely relevant

・・

ᴛɪᴘꜱ ꜰᴏʀ DeepSeek ᴜꜱᴇʀꜱ: DeepSeek-R1 is more intense — great for drama, angst or violence, but can exaggerate. DeepSeek-V3-0324 is milder, though it's prone to repetition — good if you prefer calm scenes or fluff. Feel free to switch between them anytime for a change of pace! Recommended temperature varies per model and your style (I prefer ~0.5 with R1 free).

Creator Notes

・・

I put a good amount of time and effort into constructing the definition and capturing MacCready's personality and behavior properly. Please do not copy my work and do not reupload the bot, not to janitor, nor to another site. 🙏

I love reading reviews and your feedback is always welcome! 🙂 Feel free to leave kind words, share constructive criticism, tell me your roleplay stories, or offer any tips you think could help improve the bot. Just please be respectful! Offensive or abusive comments will be deleted.

If you'd like to reach out, you can message me anytime on Reddit. I use the same username.

Thank you so much for reading! Have fun chatting with the bot!
