You guys make me remember the words of my grandfather. He only had one metric for determining whether or not a movie was good: entertainment. Basically, as long as it wasn't boring then it was a good movie, regardless of the reasons you liked it.
If a game played with friends is a vehicle to having fun then it's a good game, regardless of any other factors. There might be better games for you to play together, but does it matter? If you had fun playing a game then it served its purpose.
