And I think I can speak for virtually (but certainly not) all of us....
This is NOT a game you will master in one session unless your real name is Lt.Cdr. Data, in any of it's various incarnations. Personally, it is so deep in scope that I would start with stock vanilla until I got anywhere near a handle on the depth of preparation, pre-planning, planning, and revised planning before coming into contact with the enemy, and then throwing most of that away and pulling things together to start preparations against the opponent - even if it is AI. Get you feet wet on that, and then dive into CHS, which is a tad easier than RHS, and then get ready for the ride of AE.
