Fish the crater lakes of exoplanets with the real gear from Fishing Planet.
Space Angler — a solo SpaceEngine × Fishing Planet mashup.
You fish IN SpaceEngine: its window is the world (the “Y to fly” button brings the camera there via an official .se scenario). Space Angler is just the fishing rod: a compact panel with destinations, rod, casting, bites (beep), a tension-based fight adapted to gravity, weigh-ins, and a logbook.
Both real games open side by side. 3 destinations (Lac du Cratère Kepler on Earth, Lacs de fonte on Callisto, Fissures à geysers on Encelade), 7 fish, and 2 rods verified in your copy of Fishing Planet at launch. Nothing from the games is copied: without both games installed, you can't fish.
Single-player, in French. One click on Play and you're off.
