Why does the core engine say free for a limited time? I thought the core engine would always be free? Correct me if I'm wrong.

The more I think about it, the more I dislike this pricing scheme. I don't like paying for upgrades/patches, if they just charged me for new scenario packs I wouldn't mind.

So you are saying it will cost $100 a year ($50 for each update) to stay current with the system? And these are just engine updates, not new scenarios which will cost an additional $30 each?

I have the Matrix version of Battles from the Bulge and Highway to the Reich (second edition). Does this add any scenario or other content to those two games (besides the engine improvements mentioned above and the NA stuff)?
