Blow is designing and implementing a language for making video games, and in particular, for making Thekla’s video games (Jon’s game company). Blow does not make mobile games, nor does he make small, retro-style games that would typically be run on a Pi. His concerns are modern Windows gaming PC’s and the big three consoles. While Jai is Turing-complete and is ‘general-purpose’, the implementation serves Blow’s needs first and fioremost, so the chosen targets make sense in light of that.
