A good way to at least get an indication if a lot of people liked (or didn't like) a game is to take a look at the GameBoomers' List
of favorite games. This list was voted on and compiled in June 2007, so it doesn't reflect games that were released after that.
If a game appears high on the list -- like The Moment of Silence, which came in at #20 -- it's a safe bet that it isn't a game that most people hated.
If the game is barely mentioned, there's a greater chance that people didn't like it -- though it also might be a game that is so new that hardly anyone played it, or it may be a game that is so obscure that hardly anyone can find it.
