Yeah, the prime meridian selection is the actually colonial part of the Mercator map. It's not like they were trying to make Europe look big, but they were trying to make London central.

The prime meridian being the least skewed area of the equal earth and Robinson projections, with their bulgy nature, actually serves to make them both offer somewhat inconvenient depictions of places like Alaska and New Zealand and Japan.

Mercator is far more globally evenhanded in that regard, being a cylindrical projection.
