I would go for the tiered table. The tech trees are novel and more in tune with different disciplines, but I feel the mechanics of them are slightly irritating/limiting in Starbound. A tech tree might be nicer only if paired with quests/NPCs such as in the outpost. Regarding the standard crafting table, if people want everything from the beginning, they'll just /admin anyway. I think it would feel more respectable to have your mods in line with established vanilla-y Starbound lore.

PS: I've been following your stuff on Starbards/Serenity for a couple years, and just wanted to say thank you.

(Thank you <3 your support is what keeps this alive and kicking!)

You are absolutely right. I also think that the tiered table is the most seamless solution possible.
Thank you!
