Best of it: it's a .exe, you just open it and click a button to patch. A must-have for anyone who just want to play the vanilla experience in a modern-day PC, but without the hassle of searching, downloading and installing dozens of mods or altering the game. (I also recommend the New_Lightsaber_Blade_Model_K1 1.0.0 mod if you want better lightsaber effects, but that requires just a little bit more of fiddling, as it needs TSLPatcher)
