The mechanical complexity? the graphical complexity? The volume of content?
Yes, yes and yes.
The size on disk?
Indirectly, sometimes. Also, how polished a game is.
At the end of the day, people severely underestimate the last 10% -- which take about 3-30 times as long as the first 90% -- of creating a game. Creating a bare minimum Binding of Isaac clone can be done in 48 hours. Creating a full sized Binding of Isaac competitor will take at least a year of full time work of someone who knows what they're doing.
