First of all, this is a play style. Not a request for a self found mode. If you are looking to flame for that, look elsewhere, since I don't want a mode either.
This is not the end all, be all of playing self found. This is simply how I'm playing it, and the rules I force myself to abide by.
First off, I had 10 slots in use on the US realm. I was reluctant to delete a character, just to do a self found one, plus my stash was a bit full for the same reason. So I decided to change realms. Little did I realize just how much impact that has on my game. First off, the RMAH is disabled in any realm but your own. Not that it matters since I won't be using it, but it was cool to know. Its like playing in Hard Core.
I then let the game come up and it presented me at random a male witch doctor. So I went with it. It was like starting completely over with a brand new game account. Then I changed the game from MP0 to MP10, and begun to play. No gold, no items, and a newb of a character. But so far I have been having a blast, in my own way.
Rule number 1: I only use items that I pick up while in PVE areas. This means loot from monsters, chests, rocks, jars, anything in the map that can be opened or broken or killed. I pick up all items, even the crappy stuff, for the time being.
Rule number 2: I do not use the Auction House for anything. I do not buy, I do not sell. I don't even open it. I will even put up a screen shot of it, once the realm is back up if you all want.
Rule number 3: I do not buy any items for my character from in-game vendors. No gear, no potions, nothing. I do permit myself to sell items I can't salvage to the vendors for gold. The only exceptions to this rule, would be for items required for certain achievements, such as the Whimsy staff for example or archon armor plans, stuff that you can't get anywhere but the in-game vendors.
Rule number 4: No trading with any other players. Period. But playing with them is permitted. My concern is someone tossing something and I pick it up on accident. lol
Rule number 5: No trading with other characters in your realm/account. Gold you can't help, but if you are playing self found the way I do, gold isn't an issue anyway.
Rule number 6: Blacksmithing. I use the blacksmith, but I salvage every blue and yellow item I pick up or upgrade from, at least for the time being. Those become materials for crafting hopefully better pieces of gear later. Crafting is allowed on my game, as I have to find items to salvage in order to be able to craft in the first place as well as pick up pages, tomes, and gold.
Rule number 7: Jeweler. Same as blacksmithing. You can only work with what you pick up. So upgrading gems can be slow, especially at the beginning. Obviously it makes life interesting. But since I have literally been picking up everything, so its not so bad now.
Rule number 8: I simply have fun. Currently I play alone, as I have been tediously taking my time, hitting every nook and cranny, but here's the thing. With it being on MP10, I only have hit each area once. I might hit every cave, room, etc on each area I go through, but I do it only once. I try to play through a quest section, so I don't have to restart in the middle. And yeah, I ended up at level 35 when I killed Diablo on MP10. (That was tough even). And I have been killed a few times, but less than 10. Which I didn't think was that bad.
