Yes of course, after years and years of gaming I've definitely picked up the ability to see myself what's a good game and what's a less good game. 🙂
I usually have my pre orders in way before reviews hit the street. But in the cases where I'm a bit unsure about a game, then it's good to have the reviews available to decide whether to get it or not.
This wasn't the case with R2 though since it's been on top of my most wanted games list for a good while.
