Fancy catching some creatures? How about directly in your terminal window? Pokete is a free and open source Pokemon-like. Just like the classics it features various creatures across different types like Plant, Water, Fire and they all have their own strengths and weaknesses.
It's currently in active development but it's already quite playable with a long list of features. In the last month it only just had another major release adding in smarter NPCs, achievements, fights with multiple Poketes, in-game time for day and night Poketes encounters and you now get transported to safety if all your Poketes faint during a battle just like a certain other game.
Pretty fun idea for a terminal game really, can't wait to watch it evolve.
