Can't really answer your question as I've only played Ground Zeroes myself. However, if you're interested in getting the whole package with Ground Zeroes and all the DLC included this is also a great deal: https://uk.gamesplanet.com/game/metal-gear-solid-v-the-definitive-experience-steam-key--2857-3 (£5.89 = ~$7.65)

The Definitive Experience (as linked above), is frequently on sale lately, so is probably a better buy if you want to wait for it to be restocked on Fanatical or wait for the next sale.

I bought them last sale and still haven't played them so can't say if Ground Zero is recommended or not.

Oh and Fanatical also has Phantom Pain for cheaper AND still in stock according to my page!
