There is no such thing as a dated method for creating a 3d game. There are many kinds of games and many pros and cons for creating them different ways. It is popular these days to tell people to use Unity3D, and it is an amazing tool but there are also downsides to using it vs rolling your own thing from scratch too.

Royalties, risk of you game ending up unplayable in 10 years, running into limitations you can't fix because you don't have the source, performance ceilings you can't change, bugs you can't fix.

On the other hand if you do things from scratch you can spend years and years and years.
