built a farming game in 5 weeks with claude opus 5.5 + unity 6..

it already has a steam page

the trick is turning ideas into task cards and letting agents grind through them. here’s the workflow:

• step 1: connect opus 5.5 to unity 6 with unity’s plugin
• step 2: prototype: a drivable tractor that cuts crops and earns money
• step 3: tune the feel: handling, camera, falling crops
• step 4: build the loop: sell > upgrade machines > unlock fields
• step 5: models: concept art > tripo smart mesh p2 > opus cleans them up in blender
• step 6: turn every idea and bug into a task card and let agents work them overnight on separate branches
• step 7: auto-check every card (build, tests, a test drive) and review it all each morning

who does what:

opus 5.5: almost all the c#, split across agents
unity 6 + mcp: inspect scenes, change values, screenshot, play the game
tripo p2: the tractors, machines and props
blender + mcp: scripted cleanup before import

and the rule that saves the project... never trust the agent’s own “done”. build it, test it and drive it before you merge (dev: SirKnighty)
