no, you wont, because you will be running the updates "expansions" from FFXI's engine, which in turn will not make any difference, but i think that getting the bare minimum its REALLY not worth it. (engine is just the bare bones on the game that runs the game, for example, Half life is the engine, and Counter-Strike are mods that run OFF the engine).
::EDIT:: as long as you can play FFXI (original) fine, with little to no flaws, then any other expansion that comes out will play the same way... hope this helped
