The Sid Meier
Framework
Interesting Decisions & Systems Design
Sid Meier understood that great games emerge from systems, not scripts. Sid Meier's design philosophy, how to frame player decisions, when to add constraints, what to playtest for, is captured in this framework, captured in this framework as mental models, decision heuristics, and the signature questions they would ask.
The interesting decisions & systems design framework distils Sid Meier's documented approach into a .md skill file you can load into Claude, ChatGPT, or any LLM in seconds.
Where most AI personas generate generic output, this framework is grounded in real documented work: interviews, writing, published frameworks, and the specific decisions Sid Meier made when it mattered. Use it for decision-making, writing, strategy, or any situation where you want your AI to think with Sid Meier's distinctive patterns rather than a default model voice.
A glimpse of Sid Meier's thinking.
A game is a series of interesting decisions—choices where multiple options feel viable, consequences matter long-term, and players understand the tradeoffs. Systems should be transparent enough to strategize around but complex enough to surprise you.

What it does with a real question.
A founder is deciding whether to take a large but difficult client.
Take it, but only as a bounded bet. The reason this decision is hard is that it is a good decision: both options are viable, and each one hurts somewhere. Passing preserves your focus and your sanity. Taking the client buys revenue, credibility, and a forcing function for growth. If one of those obviously dominated, you wouldn't be agonizing.
So stop asking whether the client is worth it in the abstract and look at how this choice cascades. A large, difficult account touches your cash flow, your team's morale, your roadmap, and your other customers' attention all at once. The danger is never the headline fee. It is the quiet drift where one client's demands start setting your priorities. Founders who regret these deals rarely regret the work; they regret that it crowded out everything else.
My position: say yes, but design the downside before you sign. Cap the client's share of revenue at something you can survive losing, say a third. Price the difficulty explicitly, because if they are demanding, the premium should reflect it. Define scope tightly, with a paid change process for anything outside it. And decide in advance which person on your team owns the relationship so it doesn't leak into everyone's week.
Next move: this week, write the exit terms and the revenue cap into your counteroffer. If they balk at reasonable guardrails, you have learned how difficult they will be before it cost you anything.
The full framework carries five models, decision heuristics, signature questions and a worked example.
