Currently the tools that are key to starting a for are Pick, Ax and Anvil. If you fail to bring these with you your in trouble, fortunately the default embark profile will give them to you.
If more tools are added and they are equally necessary I would recommended that the embark screen be upgraded with a 'recommended stuff' check list. Anyone who remembers Oregon Trail will remember the useful recommendations provided at its equivalent embark screen. A checklist is passive so it dose not limit or encumber experienced players and it is a boon to the noob. A simple list of items that can be scrolled through and an accompanying written description and recomendataion, for example a brief recommendation for picks would look like..
"Picks are used by Miners to excavate rock and soil along with valuable metal ores and gems, Picks can only be made of metal and thus a pick is necessary to obtain the metal ore to make more picks. A pick will be used as a weapon if a miner is in combat but it is weaker then a real weapon. It can be hard for a new settlement to create its own picks thus it is recomended that two picks be brought incase one is lost or destroyed"
The recommendation list would have a few more general categories like 'Seeds' and 'Drink' if the item/s is lacking its name appears red in the list, if partial yellow and if sufficient to meet the recommendation its green, perhaps even another color for excess.
A simple 'hard' recommendation set (one which always recommends the same equipment for all situations) would be enough to prevent noobs from wandering into the wilderness totally unprepared and without important tools. But a system that actually considered the embark area (stone types, vegetation, climate, hostile neighbors) and could alter its recommendations based on that data would be even more useful and would be useful to intermediate level players who are exploring a wider variety of starting locations.
