None of you know, but I too aspired to become a roguelike coder once upon a time. Of something not totally unlike Urw. But I decided it was too much work. Later I began making crafts for a living, hunting and fishing in real life, regularily helping out with reindeers too. I come from a family of fishermen-craftsmen. (I'm saying this because I've been besserwissering around a lot here on the forums lately. So take this as a sort of claim I know something about what I blab about. I'm not always right, though, and happy to admit it when I'm not.)
Anyway, here is a visage of what I envisioned fishing to be in that game of mine:
1. pic) fish is splashing
2. pic) the character makes a successful spot check
3. pic) the character carefully wades into striking range
4. pic) notice how fish changes to its proper color when caught

I've been carrying this mental image for two decades. I had to write this somewhere to finally let go of this persisting memory. Thank you for reading.
