[What game do I buy?]

Thanks, everyone, for the responses and advice. I’ll go with BN and go from there. 

[What game do I buy?]

Returning to this game after nearly 20 years. Played Beyond Overlord ans the Russian Front expansion - liked the former better. There are so many versions of this game on the web site. What is recommended version to buy? Seems like so many options. Thanks. 

[What game to buy?]

Hello. A friend and I are returning to this game after almost 20 years. We intend to play asynchronously, as we both work, have familes now, etc. (Is this still done via email, or is it streamlined now?) Main question: Which version of Combat Mission should we buy? Which is the most up to date? We played the original and loved the WW2 Western front setting, and didn't play the Eastern front expansion as much. 

Thanks.
