I'm busy building one. Works great and construct is fantastic. You can use construct for free to learn, try out. The real hinderance for free version is 100 events. My Boardgame is currently under a 100, it was a lot more (I brought license), but I optimized so now it is under a 100 again. But I am not finished yet so expect it to go up again. But 100 events is enough to give you a true perspective.
Lots of plugins for board games too. (movement type stuff)
Very cool software -having loads of fun with it.
