So you buy both versions of their games if you wish to keep your old save file.
If I buy both versions I can still only restart my game once right?
Yup. Buy one version, beat it. If you want to restart but keep your original file, buy the same version again or buy the other version, beat it. Simple way of them making money. --- 3DS FC: 2449-5859-9691 Pokemon X IGN: Drench Spear http://img.pandawhale.com/post-14959-Jim-Harbaugh-tantrum-gif-CaXs.gif
