What games do you refuse to play despite overwhelming critical acclaim?

I remember when ME2 got a demo for the PS3 (it was Xbox exclusive at a time) and I was blown away by it. ME2 is absolutely in my top 5 gaming experiences ever.

Similarly/not similarly, Mass Effect 1 is one of my favourite games of all time and at one point was one of very few games that came close to challenging MGS1 for that for me. My last playthrough of it was my 6th and even at that stage I was still finding new things in the game including quite a long conversation on the Citadel that I had no idea existed.
