This is just dirty on Rockstar's part. I can understand a partial download. We should expect that as far as third parties go, buying physical just means that you can use less SD card space to play the game.
I can even understand why bigger games may cost 10 bucks more for a physical copy due to higher capacity cards. Fine, I can deal with that as long as digital remains the same price as the other platforms.
What is unacceptable though is using a smaller card (32 gig can fit this game) and STILL requiring a partial download/install and STILL charging 10 more for physical despite using the cheaper cards anyway. This is UNACCEPTABLE! If you want to charge ten more, use the correctly sized cart!
I had no plans for buying this game as I already beat it on PS3, so the mystery aspect has already been spoiled for me. If I were to buy it though, I would go digital as eventually getting an SD card for 3rd party games will pay for itself down the line. I would show RS that I support their games on Switch, but not support their physical release strategy until they do it right (either partial install same price as competing platforms or use a bigger cart).
Like I said however, I have no plans to buy this game anyway. I just hope those that do go digital so they can feel the sting of their poor physical release strategy.
