What Inselkampf was
The game where you expand your island. Inselkampf was the classic browser strategy game built around exactly that — settling an island, raising a navy, and contesting the archipelago with other governors in real time.
Inselkampf — German for island battle — was a free, browser-based multiplayer strategy game developed by Sven Schramm and launched in 2005. You started with one island. You raised a Main House, a Lumber Camp, a Stone Quarry. You queued research at the Laboratory. You built a Harbour and, eventually, you found the nerve to send your first ship across the water.
Time mattered. Construction took real hours. Fleets took real hours to arrive. A raid you launched at midnight wouldn't resolve until morning. You'd check in twice a day, queue an action, and find out what happened later. Battles were resolved server-side; the report appeared in your inbox.
It was, in retrospect, the slow-strategy sweet spot: deep enough to think about, slow enough to live with. Surprisingly cruel, deeply social, and unmistakably its own thing.
