Play Testing a Space War App

I found a great blog post: “Play testing a game design the low fidelity way”, written by Chris Khoo. It came at a good time for me because I was stuck last year, not making much progress on my Space War app. The reminder about play testing was good, but what helped me the most was the “low fidelity” part.

Chris Khoo’s situation was similar to mine. His goal was to “build a game which casual strategy fans could easily pick up”. The challenges he faced included the “cumbersome user interface” and the problem of “too many commands available to a user at any one point in time”. In his blog post, he describes how he began a redesign and started it with paper and pencil prototypes and old board game pieces.

See the full blog post for more about play testing, low fidelity prototypes, and the test session I am conducting for my new app.
