Owner

Master tracker for building a small Ultima Online-style MMO playable among friends. Realistic ordering — combat comes late, after stats/skills/mobiles. Each milestone below is its own epic issue.

Foundations (in progress)

#1 — Migrate client from Godot to MonoGame
#2 — UO-style binary asset container

Milestones

#3 — M1 — World & character persistence
#4 — M2 — Tiled map & server-validated walkability
#5 — M3 — Area of Interest (spatial partitioning + local chat)
#6 — M4 — Ground items
#7 — M5 — Inventory & equipment
#8 — M6 — Stats & use-based skills
#9 — M7 — NPCs / mobiles with basic AI
#10 — M8 — Melee combat & death
#11 — Cross-cutting — hardening & ops (pre-internet)

MVP target

A first shareable build = M1–M4: a persistent world with a real map, where friends see each other, chat locally, and pick up items. M5–M6 make it an RPG; M7–M8 make it UO.

Guiding principle

The server stays authoritative; clients send intents only. No milestone ships a rule that can be enforced only client-side. Every epic carries its own Definition of Done.
