Most people didn't buy a retina macbook pro just to play D3. Most people consider than a luxury bonus they are getting. It's not like Macbooks are well known for gaming but this is the first time in a laptop where we can actually play modern games. Just to shorten the divide between pc gaming and mac gaming.
That is all. If you can't see why we are so interested, then you clearly missed it.
I can understand the need to "tinker" but if you are into gaming this isnt the machine for you, Ive been playing with the NRMBP 15" and it isnt up to dealing with DB3 compared to the Samsung series 7 gamers laptop.....nor BF3
