Ok…so, magic food and shelter but nothing else. Then the first thing you’d need to do is start building tools. You don’t have to hunt or anything like that, so you can devote everyone to the basic technology projects. I’d say, first thing you do is produce stone cutting tools that will allow you to work wood. Cut wood to allow you to build the infrastructure to create a mill of some kind (this would be a major task without tools, mind, you could devote a lot of resources to it). Once you have the mill in place you can use it as a power source for all sorts of things. At the same time, you will probably need to start looking around for minerals in the area (unless you are giving a magic map as well, detailing where things are). Assuming the area you are settled in has all the stuff you need, I think the first order of business would be to find some copper and tin deposits and produce a low order smelter. Since bronze can be cast, and since it doesn’t take as much technology or heat to produce, I’d start there…start producing bronze tools to replace the stone ones, and start integrating bronze tools into the mill (saws, hammers, etc).
Once you got a good base of bronze tools, you can probably expand the mill to provide more power, and start thinking about…iron. Cast iron isn’t that difficult to make either, and you should be able to build out a better, more efficient smelting and forge system by now. In addition, some resources need to be committed to pottery and ceramics. Since you have magic food and water (and medicine?), you can break people up into their specialties. I’m not sure WHY you would do all this, though if it’s a game to try and get to 21’s century tech then I guess that’s the end point. So…bronze to iron. Develop pottery and ceramics. Power from increasingly more sophisticated water wheels. Possibly develop a glass industry as you will need that later as well. Paper and leather manufactures (when the magic food is given, will they give the brains and skins too? If not you are still going to have to hunt). As you build out the tools to build the tools to build the devices, you can think about things like printing presses and such. Unless this group is plunked down right smack in the middle of all the necessary resources they are going to have to go out and find stuff (coal and coke would probably be next).
Bottom line is, it’s going to take this group longer than their lifetimes to build up to even 19th or 20th century tech levels. Oh, they could probably build some vertical tech that is more advanced (electricity, for instance, could be developed fairly easy, and I suppose they could use it for electro-plating or even telegraphs and such), but overall it’s just not something you could jump right into. You would need to develop a chemicals industry and all the tools associated with that. You would need to develop tools to do machining for things like steam engines. You’d need to develop transport and logistics systems to go out and get all the stuff that you will need to build the stuff to build the stuff to build the devices that will let you build the stuff that finally gets you to whatever goal you were actually after. I suppose with magic food and such you could potentially have millions of people involve, which would hurry things along somewhat (and lessen the risk of key people dying…though maybe if it’s a game people won’t die either), but assuming a couple of thousand people involved I think it would take several generations to get even in the ball park of 2010 tech…or, as I said, even in the ballpark of 20th century tech. Or 19th century tech.
JMHO though.
