Herr Doktor,
Version 1.03 was definately riddled with "bugs", that made the game unplayable. The bugs were fixed in the latest version 1.04 release.
If you liked EFII, you can still play it with it's original feel.
One non-optional change is that small AT units will now have a higher chance of remaining hidden, even after shooting.

That could catch you by surprise.
The addition of optional rules, variable visibility and extreme assault, will need to be learned if you want to use them.
Though, I personally do not recommend them if you want the fun of the original game. :rolleyes: :chin:
It's still well worth the price. :smoke:
