-google creative board game. then u will find there are still a few company doing quite well and their product is very very creative.
-subscribe to podcast "have game, will travel". this guy review board game and card game and RPG(that old time dice version not the video game version).
-google board game related conference. like Dragon Con, is mainly for fantasy writer but i think there are some ways you can chip in.
-in my country there are this cafe posses 100+ board games that will loan to customers. i heard this is a franchise from a nearby country, so can you imagine how big they are.
and here is the study:
-board game focus on people than technology. good idea and game play is the key but not better graphic and 3d model.
-real human interaction is the key. So, create a board that allow imagination even with basic rules to fulfill. I always bend the rule by borrow money for investment while playing Monopoly with my friend, we all think is more fun.
-easy to cross platform. is easier to port to video game than video game to board game. my friend had their most boring board game session while playing World Of Warcraft Board Game(which WoW is the most successful video game ever exist on earth).
-Tetris as the benchmark. simple gameplay and after many years still the top download game for mobile phone user around the world. reason, easy to play.
market is still there, is how you run it is the key.:)
hope this help:)
