I used (and still occasionally do) to write reviews for games, including RPGs and I was not always kind. But being on the inside, you realize how subjective these reviews are. People play RPGs for different reasons. Some love story. Some love the tactical side. Some love the character development. So I might like a certain game for its potential for story but the system may be crappy for a person that loves tactics.
As a result, I rarely look for reviews but if I do, I go to Youtube and search on the RPG name with “review” at the end. I do not have a go-to site because there are so many and not all of them cover what I am looking for. Sometimes, I look within the DriveThruRPG entry for a review but I find it easier to watch a video.
Additionally, I have the benefit of being heavily involved in the local tabletop gaming convention scene in that I plan 4 or 5 gaming events a year, including MACE in Charlotte NC. I get to see a lot of games being played, opinions being shared and GMs rise and fall. I get a lot of input and opinions (whether I want it or not) from various GMs and sometimes I sit in on a game if I am very interested. It is how i got exposed to Savage Worlds, FATE and others. I see the games being played in practice and form my own opinions there. A gaming convention is a great way to try out games, sometimes better than just reading or watching someone else’s opinion of it.
