I'd echo Gog's comments - excellent review, and there's been some decent writing on here recently (haven't read your LA Noire review yet as I thought I spotted some spoilers in the first draft!). Good to see!
I would just say that you go a little bit overboard in some bits. For example, I think this is a bit harsh:
Sonic Team seems to have finally caught on to how much everyone hates both the writing and voices of recent Sonic games, and has approached this problem with the purification strategy: get rid of all of them and replace them with people who don't suck at their jobs.
That's about it, really. The rest of it rocks.
