You don't plan a 1700 employees company just for SC/SQ42.
This is Chris Roberts we are talking about. He very well might be. Or maybe you're right, he's going chasing other projects without delivering on the projects he's already taken money for. That would be quite like Chris Roberts.
After the release of SQ42, they will earn money they could spent wherever they want.
But SQ42 is not released and has no release date, but they are planning that office right now. They are planning the expansion of staff right now, the money they have right now is money given for SC/SQ42. The money they are investing in the Frankfurt office is money give for the development of SQ42/SC.
If they are planning all this and the expansion for a different IP, they are doing it right now using funds given for SQ42/SC.
Perhaps you could make these arguments if CIG had released a product and sold it. They haven't.
