Yes, it is similar, and it grew out from my experience with that website. However, I found HabitRPG problematic for a number of reasons. First, the rules are such that I "died" even if I failed to complete a small proportion of dailies. Second, I had little freedom to assign different value points to different tasks. Finally, my system allows me to manipulate the data in all sorts of ways, and create progress graphs that are more informative and motivating than those in HabitRPG.
