This is my systems-first game design corner: where I share practical artifacts, scorecards, and memos I use to ship under real constraints. Below are selected, self-contained documents intended for stakeholders and designers to align fast and iterate with numbers.
Two dedicated rubric pages are maintained: one for RPG classification and one for Extraction Shooter systemic analysis. They are intentionally separate because they evaluate different design problems, with different scoring models and decision criteria.
Open RPG Rubric
RPG PDF
Open Extraction Shooter Rubric
Extraction PDF
Game Loop Primer Helldivers 2 [PDF, 2 pp]
Download
TL;DR: A stakeholder memo that disambiguates core / progression / meta / playerdefined loops using HD2, maps the real core loop (Pick Land Extract), and frames time as the primary antagonist driving risk/reward and cadence.
What to look for:
Case Study Entropy Microdemo [PDFs + Repo]
Open Case Study
TL;DR: A/B seeding (PRNG vs ERIS) across multiple LLMs; highquality entropy alters exploration paths, reduces certain failure modes, and surfaces more structured behaviors in capable models.
Case Study Die Roller Demo [PDFs]
Open Case Study
TL;DR: 100k+ d20 rolls. ERIS preserves variance and resists local minima; PRNG stabilizes into uniform mimicry. Exploration vs fairness.
PostMortem POV: Pixelshift [PDF, 12 pp]
Download
TL;DR: Prototype ownership under shifting scope. GDD POC prototype; multiple systems integrated; risks, pivots, and Unity migration documented so delivery didnt roll the dice.
What to look for:
Primer Prompting, Tokenization, and Input Parsing for Games [PDF]
Download
TL;DR: Prompt outcomes hinge on set theory and semanticsnot rote arithmetic. Disambiguate scope, units, and partitions (singular vs plural; one word vs a list) to avoid gotcha prompts and yield stable, checkable answers.
What to look for:
Applied Metaphysics of Game Design Entropy & Information Systems [PDF]
Download
TL;DR: Randomness becomes visible when fair PRNGs settle into attractors (local minima) that feel stuck. Treat games as applied metaphysics of state and entropy; favor temporally aware (1/f) randomness with memory so long sequences stay fair, exploratory, and surprising.
What to look for:
Castles Burning 4page jam RPG [PDF, 4 pp]
Open on itch.io
TL;DR: Constraint exercise: shipped under a hard 4page cap with a novel existence lever. Peer feedback flagged the premise as captivatingly alien and asked for appendicesexactly the next step postjam.
What to look for:
Release Snapshot: Publisher: White Wolf | Title: A Fourth Axis: Modern Blood Composition | SKU: MIOTHEZDIHST0001 | Units Sold: 120+ (3 months)
New to integrating content into established IP workflows; iterating and improving with each release.
