The battles have key tactical decisions that make sense too. I've read the comments on the artillery tactically not working correctly and can see where that's possible (all artillery advancing) and I'd like to see someone post what the original rules were that required an infantry unit be present with artillery for it to function normally.
I've looked it up: the 1st edition rules had a simple exception: if no friendly infantry or cavalry are present in the same battle column, artillery only fire at F1 at engaged units. Actually, that rule does not even seem enough to prevent abuse, as a single infantry unit can cover for any number of artillery units. Maybe each friendly infantry (not cavalry) unit present should allow one artillery unit to fire at F3?
I have played both the eastern (Bobby Lee) and western (Sam Grant) theater games and prefer Bobby Lee, Although Sam Grant does a great job historically representing that front...
We found Sam Grant horribly unbalanced in favor of the Confederates. In the 1862 scenario, the US have to take the initiative vs. an opponent who has them outnumbered, in difficult terrain. Didn't work, and didn't look like the war in the west at all. I do have a homebrew scenario for SG though, that I believe does a better job. It's posted in the SG file section if anybody is interested. It would be nice if CG could redo the SG scenarios officially, the game system itself is quite good.
