the best thing about that game is that you CAN do something like walk away for a while and still be able to play it straight away. This is because there are only 2 buttons used.

I walked away from Witcher: Wild Hunt for 2 days and when i got back in i was running into fences and getting killed by packs of wild dogs 7 levels lower than me as i wildly swung my sword in various direction and forgot how to parry.
