Husband and wife board game design team Sheila Santos and Israel Cendrero have been collaborating on their creations for almost a decade - and have sealed their status as notable eurogame architects in recent years with standout titles The Red Cathedral and The White Castle. The pair - who go by their board game design monikers Isra and Shei - sat down with BoardGameWire to talk about their journey into the industry, why working as a duo is essential for them, and the major error they see new designers making when pitching to publishers.
