The game was tested? Wonder how PTW didn't actually work when released then? Or do I not remember that fiasco accurately?
Anyway, seems to me most of the supposed testing was functionality of the program, not its game qualities. Otherwise the unbalancing wonders and such added to the 'expansions' wouldn't be there, no?
And by sliding scale I don't mean the handicap is a function of how the player is doing. I mean having adjustable difficulty at different stages in the game - simplistically, play the Ancient on Monarch, the Medieval and Industrial on Emperor but the Modern on Diety, say. Right now the Ai gets a BIG lead in the Ancient era, and the whole game is a catch-up race - and once you catch up, it's basically game over. If the game got more difficult in stages, that would be addressed. (It could be a pre-set thing, or adjustable by the player. It matters not which.)
The lack of functionality in the later game difficulty settings shows a failure to tune the gameplay - they tested the pretty graphics and menus, not the game.
Anyway, I'm wasting my time at fanboy central, I should have remembered that.....
