I loved this almost rpg-like aspect of Panzer General. Making you attach emotionally to your "hero units" is a good thing, in my book.-a few quality units are MUCH stronger than a lot of garbage units.
Lets just hope Civ5 doesn't repeat the mistakes of the latter games in the series (mainly People's General); where modern units had such high attack strengths that no unit could survive any length of focused fire.
I quickly stopped playing those games in disgust when I realized the computer could take out any unit it wished to.
I mean, I don't have a problem with this in a game like Civ4, but PG started out as a game where during your campaign your units survive and become elite.
The latter installations of the series destroyed that.
