I used to work for a crown crop that relied heavily on a legacy software. The team responsible for developing and maintaining the software was mostly useless, only 20% of team was actually qualified and productive.
The guy that was basically carrying the team by himself made a modernized, working prototype of the software in the latest Microsoft MFC at the time, showed it to his boss, but was told to do it on his own time. He got fed up and left, and this mistake easily cost this crown corp millions of dollars hiring consultants (because employees are useless) trying to recreate what this one guy was trying to build. Unions are great, aren't they.
I wonder if something similar happened at SEGA.
