I have 45 gamer points on Xbox Live. I'm mightily impressed with that, as it's 45 more than I thought I had. Those points were earned playing Pinball, Solitaire and Mahjong on Windows 8, apparently (don't have an Xbox; I'm PC gaming master race).
There are many PC games including BioShock, Gears of War, and Halo that have Xbox Live gamerscore. The point is with this Xbox live eco system, we have only 1 list of Cheevos and we should stick to it. It's just not right and it's going to confuse people.
For for these visual studio cheevos, when people put on their resume I have 67 Cheevos. What is the person looking at the resume going to think? Visual Studio Cheevos or Xbox Live cheevos. Now I have to put 2 lines on my resume
95,000 Xbox Live Cheevos/Gamerscore
67 Visual Studio Cheevos
I really haven't tried getting VS cheevos yet, so that's why my score is low. I'm not even sure if I'm going to try now.
