Well I'm glad you're enjoying the game, like I said I had a lot of fun with it.
How to get rich in SWG:
Save up enough credits from doing missions and selling loot to buy an energy harvestor (windmill) and a couple of small mineral and chemical harvestors (you'll need the energy from the windmill to power the min and chem extractors).
First set up the windmill and save up a couple days worth of power. Then set start mining metals, ore, and fiberlast. Look at the stats and try to mine the stuff with the best numbers. Then take it to the market. Look at the market for whatever you're selling to see what price others are selling the same stuff for and sell at a slightly lower price.
As you accumulate credits build from a couple of windmills and small harvestors to solar collectors and mediums and then to fusion power and the largest harvestors. This building process took me a couple of months without any help or "gifts" from other players. For me there was some satifaction to building from the ground up without any shortcuts. If you go this route you may not have a lot of liquid cash during this time, because a lot of it will be re-invested to buy better harvestors, weapons, armor, buffs, a house, etc.
Once you have a lot of credits it's time to become a one-man vertically integrated operation. 😎 Buy a couple of factories and start looking at stuff to make from all of the raw materials. Almost every piece of armor, weapon, vehicle, etc in the game is buildable. You can either train a crafting skill and make your own schematics, or nicely ask someone to make one for you. You don't need any crafting skills to run a factory, just the raw materials, the factory, and the schematic (for some odd reason most crafters will make a schematic for free). I went for easy stuff that's commonly consumed, like droid batteries, and made a killing.
After 6 months I had all the best gear available on the market, about 8 million credits in the bank, and a house full of hunting trophies. I put in about an hour every couple days to checking up on the harvestors, and every week or two a couple hours to move them all when the spot is depleted and new resources spawn. The rest of the time I was out killing the local wildlife, npcs, and occasionally other players.
BTW, I was a Teras Kasi Master/Commando/Medic.
I hope you enjoy the game.
