The Standard Galactic Alphabet (SGA) is a writing system used throughout the Commander Keen series of side-scrolling platform video games developed by id Software. It is a simple substitution cypher, where each letter in the Latin alphabet has been substituted with a different symbol.
Besides the 26 letters, SGA uses spaces for its interword separation, and in some occasions a dot-dash-dot symbol as a full stop. In a level in which players obtain a pogo stick, punctuation marks appear on either side of the word “POGO,” perhaps as quotation marks. No other known punctuation exists. Numbers are normally spelled out in words.
