I drew a new world map of Teemu and placed new locations on it. It was then easier to visualize where new items would go and how they would contribute to the gameplay. The plan is now ready which is a good thing, no more wondering about what to do.
I have given up creating TEROS (TEemu ROleplaying System). It was too detailed and started to go in the direction of "never releasing it". Instead I'm going to model the damage system the simplest possible way and add only features that are needed. It's probably going to be something like accuracy and damage vs. dodge/speed and hit points.
