What have we here?
Ah...one of these...
I try to go to several places to get different opinions.
Among the many places I go to are:
Drivethrurpg, EN World, Facebook RPG Groups, Google+, RPG.Net, RPGNow, and various gaming blogs. I also get a lot of reviews from friends who have purchased it first.
There are a ton of places to find reviews, should I want them. I don't often want, or need them, but it is interesting to see what others think about a particular game from time to time.
Don't know what else to say on this one.
