>>716393634 (OP)...so imagine you make a game.
Laser tight focus on a theme, a visual language, a purpose.
Pretty good, right?
Now let's make a sequel or an expansion.
Well you just remade the same exact game, congratulations.
...But what if we add OTHER STUFF?
Isn't that exactly the OTHER STUFF that you discarded and removed to get that laser tight focus on a theme, a visual language, a purpose?
Enlarge the scope, add content, make a sequel = lose thematic focus.
It is a platonic, divine rule of God. There is no escaping it, it is mathematics, like 2+2=4.
