At the same time the D&D Next playtest came out, and they did the same thing (I have another post started on my experiences with D&D Next that I'm working on finishing). So, during this I thought...that's all I really need now, and started weeding back all the extraneous rules...of which there are a lot of...wow, eye opening.
In doing this I'm essentially creating the basic game, then using a "side-bar" system for optional rules that can be adopted by individual groups. Similar to how 2nd edition AD&D did things. Additionally with many people focusing on the hype around D&D Next I can't seem to keep myself out of some of those discussions.
I have another post on the Archetypes that I'm locking into for the Quick-Start. "Wait, What! Archetypes, I thought the initial design was complete freedom when creating your Hero!" Yes, that is true and it'll still exist but I've decided some people really do NEED minimal choices. This came out in the play tests a number of times, when I attempted to walk players through creating their ideal Hero, most suffered Analysis-Paralysis with the number of choices, the interdependence of skills and attributes, all had them frozen.
So my archetypes, which I call templates will include the staple ones (Thief, Fighter, Knight, Cleric, Wizard) that all depend on one of the five main attributes, but five additional ones that are in-between (Assassin, Ranger, Barbarian, Monk, Psion) each of which depend on one of the five sub-attributes. With these examples, I attempt to layout the "logic" behind the design.
