Given that Starbound is somewhat continuation of Terraria, i thought: How about learning some lessons about Terraria and how about not repeating the same mistakes made, eh? In this study, the main focus should be things like design, balance and features rather than terrarian content. NPCs: All of the NPCs lacked the means to defend themselves. With some NPCs i get that, but it is ridiculous that the Arms Dealer would sell ammunation and weapons, but couldn't fend for himself even against lowest possible level enemies. Suggestion: Security Guard NPCs for hire to defend your base in a hostile enviroment (note the difference to mercenaries) It was awfully hard to get the NPCs to move to their intended rooms. Best way of course was to move so far that they would simply spawn in the right place, but that was still quite problematic in multiplayer, as at least one of the players would be staying near the NPC town most of the time and having all of the players go far away from the base to get the NPCs to spawn isn't all that convenient. Suggestion: Having some well established furniture like ladders and standardized stairs that NPCs could use. NPCs lacked the instinct of self-preservation and kept opening random doors at random times. This of course lead to base designs in which NPCs keep dying to traps (that were intended against creatures) and opening doors to invading creatures or to (logical conclusion) bases, in which NPC areas were more like prisons/containers and player areas would be isolated from the unintentionally harmful NPCs. Suggestion: better NPC AI to keep them from making suicides and to, say, close the door after them. Perhaps even making way for the players (that would for example want to access a chest).
