Knights of the Old Republic | £2.49 | Mac App Store
It's one of my favourite games of all time, and now it's the price of a pint on iPad. Knights of the Old Republic is BioWare at their finest, leveraging the splendid potential of the Star Wars universe to make an RPG that's rich, compelling, fantastically deep, and filled with some of the most memorable characters in video games. Aspyr have done a great job on the port, meaning that you can now take KOTOR with you wherever you go.
Just buy it.
