In the last thread, importing from ME1 to ME2 was discussed.
You can create your own "import" by using Gibbed's ME2 savegame editor (google to get it). This method doesn't give you any of the game mechanical benefits of importing a high level ME1 character (though you can obviously use the editor to get some of those), it just allows you to set the ME1 plot flags to your preference.
To do this:
1. Start a new game in ME2. Save when you are able to.
2. Open said save in the editor,
=> Set flags under Plot -> ME1 to your liking.
=> Set Raw -> Plot -> End Game State to LivedtoFightAgain
=> Save new savegame. Note that you need to follow the filenaming format, or ME2 won't read it.
3. Open ME2, and select New Game -> import ME2 character, and select the new save.
