So like quality wise AA $5m, AAA $10m, A $1m (3x headcount). Assuming $30 preorder price, that’s 34k preorders. That’s crowd fundable. Start at A quality and grow organically. What kind of game is this? MMORPG?

It's less a question of quality and more about things like systems/design complexity, scope, and time This would be, by most definitions, not a AAA game by any stretch. The goal would be a small open world PS2-spec single player game with no combat, similar to things like Caravan SandWitch
