I'm struggling I must be honest to see why it's more enjoyable to play Arena just against people in your house than Simple Games against the same people, but I guess if it makes all the difference then fine play cardboard games. It's not like any of us can play you anyway if you mainly want to play in your own household group!
For what it's worth i play simple games with my wife if we play together, And we each play Arena if on our own so wanting to play others. We've played over 10,000 games on BGA like that now and love it.
