Two editions are on sale: Standard at $79.99 and Ultimate at $99.99 in the US, with local prices in other countries. Every purchase before November 20 includes the Vintage Vice City Pack. Ultimate is digital only, and the boxed Standard copy holds a download code rather than a disc.
Which did you pick, and what tipped it? The extra Ultimate items, the price gap, wanting a physical box on the shelf, or waiting for reviews before you buy? If you have not bought yet, say what you are waiting for.
Our editions page keeps the current contents and prices with their sources, so you can check a detail before you answer.
