Halo Reach launched to great success, as covered in yesterday's report. Its launch numbers were high and Steam user reviews are very positive on average, too.

That said, the game does come with a fair share of issues on PC ranging from audio to stuttering, from input to menu performance. Developer 343 Industries posted a list of these known issues as well as the current plans to fix them (if possible).
