If it was smart business sense then Bioware would have approached with the D&D idea. That IP was thinking of doing a D&D game and Bioware happened to have an engine that fitted the bill. That I would call luck.
The game could have been in any state at the time. It may have even been nothing more than an idea. Just because you stick easter eggs in a game dosnt mean something is always going to come of it.
See first paragraph.
