I decided that (in contrast to e.g. D&D 3) in melee combat smaller creatures will not get any advantages to hit larger creatures. While this might seem counter-intuitive at first glance my reasoning is the following:
- Larger creatures endanger smaller opponents due to their mass and violent movements.
- Smaller opponents have to be particularly careful to not be hit accidentally by movements.
- Thus the advantages of a larger target are neutralized by the danger moving larger body parts present.
Consequently larger opponents - while suffering from hit penalties - can use sweep & stomp attacks on sufficiently smaller enemies.
Otherwise sizes are what you would expect: they are ranged from diminutive, tiny, small, medium, large, huge, gargantuan to collossal (nicely represented in the page sketch displayed above), larger creatures have more hit points and move faster but are far less stealthy. But I also noticed that I need to finish the basics of the game as e.g. the hit point adjustment for smaller creatures seems to be far more dependent on the hit point base line than the adjustment for larger creatures. So I finally should get my act together on these parts to have a solid baseline to discuss. More on that in future posts.
