Gene,
I think you'll find it worth the money just for the extra PBEM slots and the op-fire filter.
The rest is a bonus.
Also the new '5' key units view is very handy, especially in a battle like the last ET where there are many units on the map.
The reason I got the CD versions and paid the cash was mostly to support the SPCAMO guys for all their hard work over the last 10 years.
Don and Andy have put in uncountable hours to keep these games moving forward.
I was even allowed a free CD because of my work on the play-testing squad...and I still paid for both games!
That's how much I appreciate what these guys have done.
Anyway...you won't regret the investment...and you just be bloody harder to beat when you can set your units to react like they have half a brain during your opponent's turn
Why don't we have a battle? ...before your CDs arrive that is :-)
Cheers
Jason
