I ran into graphical bugs during cutscenes, mouse stuttering when set on default sensitivity, and performance issues once the game opened up its world beyond the prologue. Its 2-4 hour runtime just doesn't justify the price of entry at least to me, especially when the first 30 minutes is an intro, tutorial, and exposition dump-- you don't get into the real meat of the gameplay until you step outside of the first level, and as I said that's when more issues rear their heads.
really hoping we get a sequel
