The biggest issue with XB1 is that it felt like a massive regression compared to 360 development. We were forced to use this Windows 8 stack that came with all sorts of warts: “managed” C++/CLI, confusing manifest files, complicated app lifetime rules, only push deployment initially, limited threading control.

For WiiU, Nintendo used the Green Hills compiler. Their entire toolchain was simply clunky and unstable. You had to use this MULTI debugger which often didn’t work. My favorite line from their dev docs was “c++ not fully supported”. Well, that’s an issue since we used that extensively. It wasn’t even clear what actually wasn’t supported.
