Well there are over a thousand new boardgames published every year...It depends on a number of factors such as player count, game length, co-op or no, aggression, resource gathering, party style, and then there's theme...
The biggest problem I find with more complex board games is the low player count (Usually up to 5). We always have this problem in our friend group. All of us can't play at the same time and we have to make a rotation.
