I wish I could be more excited, but having played 5e the idea of a universal proficiency bonus really dampens the excitement. The minute adjustments afforded by the skill point system is one of my favorite parts of the game. I’ll wait and see how the rules actually pan out before casting final judgements, but ultimately I’m glad there’s more than enough PF1e content to date me and my game group for years to come.
Why have the small/medium distinction at all then?
I think it's a bit of a stretch to say much about anything for race design is a hard and fast rule at this point with so few examples.
I did forget Sarcesians though. There clearly is some advantage to Large and larger creatures, but at this point the only rules interaction of a creature being Small is that Ysoki Moxie doesn't work on them, which is a bit of a shame to me. Presumably they're easier to carry but with how abstract the bulk system is weight doesn't really seem to matter unless the GM wants it to. I suppose they could fit into smaller areas too but again that seems more of a GM discretion thing.
Hmm yeah i'm curious about this too I figure we will have to find out more in alien archive surely there will be a few large or larger creatures in it. Kind of wish we would of gotten an enlarge spell.
There is also one Large playable creature in First Contact. The Haan, which is a big floaty bug. It has only 4 HP, a strength and dex bonus and an int penalty. I kind of agree on the enlarge spell, but the main advantage of it(higher damage dice) doesn't exist in Starfinder.
Stat distribution doesn't seem to have much to do with HP, especially when you consider the races from First Contact. For example the Contemplative is a medium creature that only had 2 HP. They do have a Con penalty, but so do Elves and Damaya Lashunta which are both Medium with 4HP. Not to mention that Humans and Half Elves both have the option of getting +2 Con but remain at 4 HP. Likewise Half Orcs have the option of whatever they want for their +2 yet always have 6HP. Clearly their are trends but they are definitely not hard and fast rules. See also Goblins which are small but do not have a strength penalty.
I adapted From Shore to Sea to replace the Dead in the Deep mission from Dance of the Damned.
While I had the Acisazi send the PC's to Blackcove, I wish I had just have the events of Blackcove occur in the Acisazi village instead. I also used Menotheguro instead of Mohl'omog since he's more of a threat.
