I've loved Starfinder ever since it came out, and every addition to the game so far has only deepened that, but I can hardly say I'm satisfied. I'm eager to see what is coming on the horizon, but there are some areas I'd like to see deeper exploration.
-More info on Pathfinder-era ancestries that haven't already made the jump to Starfinder. I don't care if Ysoki already fill the niche, I'd love to see kobolds in space. Plenty of classic fantasy species would do well with a Starfinder write-up, and we've certainly seen how orcs have been changed by the centuries. In a similar way, other playable species could find their own niche separate from similar alien ancestries that already exist.
-More Character Option Books. Yes, Starfinder has so far been "Less is more" compared to PF1e, but with 4 Alien Archive books under our belt, perhaps it's time to delve into expanding the various sub-genre's of sci-fi that players can explore through their character. Mechanics that have swarms of orbiting mini-drones, A bigger delving into how the Planes have changed in the millenia, and so on.
-Bigger Books in General. I know that's a longshot, but Starfinder books are criminally small compared to their Pathfinder equivalents, particularly books like Near Space, which was even smaller than Pact Worlds despite covering many more worlds!
I think I'll leave it here before I start to really ramble, but what are the rest of you hoping for in the future of the game?
Im hoping for a couple of new classes and themes, along with some material on magic post gap and if or how its changed. Along with some information around the planes... I really want to do more sci fi adventures in other realms of existence
