nope. gotta have Me2
Just get mass effect 2, and if you really can't be bothered actually completing a quick runthrough just use it to import your ME1 save to create a ME2 save, that you can then edit with the save editor where you can just set the completion flag (and other events I guess, haven't really extensively used it), then you should be able to import that save into ME3.
No. ME2 game saves store and track various event outcomes in the ME2 game which have direct ramifications in ME3. Without a ME2 game save, ME3 has no information about the major decision points it expects to be inputted from the game save.
