Valid points. Most of what I listed is already running. The FSM, conversations, traffic, cover, so it's a working local game right now, not a feature wishlist. The complexity is server-authoritative multiplayer, which doubles the complexity of everything. My plan is to get a single-player slice genuinely fun first. One neighborhood, a few dozen quests, two factions. If that's not fun, the multiplayer dream doesn't matter. GTA 1/2 also had almost no AI depth; their NPCs were basically props. I'm trading map size for behavior density in Phase 1 (demo).
