Solo dev builds FTL-like airship game in a week with Claude, shipping 7 languages and 100 achievements

A solo developer built an FTL-like fantasy airship strategy game, Magehold Fairwinds, in one week using Claude ($200/mo plan), with a free demo live and a Steam release coming in weeks.
- Approach: described the game idea to Claude and fed in an existing world bible (magic system, mage types); the first version was already decent.
- Assets: Claude listed all needed art assets, GPT generated them.
- AI playtester: had Claude write a "human captain tester" bot that played hundreds of runs in different styles with suboptimal moves, then produced difficulty-curve reports fed back into Claude.
- Automated heavy lifting: localization into 7 languages (screenshot-checking UI breakage), 100 Steam achievements with art, Linux/Mac support, and even a self-cut trailer (Claude ran the game and grabbed clips, two tries).
- About 30+ iterations total: skeleton fast, bug-fixing took 3x longer, but big updates now just mean waiting an extra hour.
