Old-school MMORPG built with Opus 5.5

Real cost for me: one full weekly limit on Max 20x. The $2,175 is the API-equivalent, and I didn't track it per feature, so I can't split it the way you asked. Closest I have: $574 main session (wires everything into Unity and fixes it) $1,601 for 161 helper agents (art, rigging, code, reviews) 98.7% of the 7.85B tokens were cache reads, it re-reads the whole project on every step. Asset generation on Higgsfield API, ~$227: $149 3D models from images $29 3D from multi-view $43 2D images $5 other (login video, music) rigging was free All in ~$2,400
