It doesn’t happen often, but it happens. The CoD Ghosts scores differ based on platform as one platform suffered from such dramatic framerate issues that it felt like a noticable step-down in quality. Here the versions are close enough that varied scores didn’t make sense, but different enough that it was worth a mention in the review text.
It’s worse, yes, but I didn’t feel like it was so much worse that it justified a half-point drop. The tech issues that are exclusive to the Xbox version exist in maybe 5% of the levels. Frustrating but not game-destroying.
The tech problems were not the biggest issues we had with this release. It’s mostly about lacking design and presentation.
Most certainly not. I’m not an expert. I’ve played through all of Evolution, though not flawlessly. But I have beaten Hell on Spleunky, so consider that my CV.
