I did my first Demo last Sat even though I still haven't heard back on my Demon app yet.

We both come from a miniatures background so I let him pick out his army after only a brief explanation of the stats and he developed an interesting undead force.
for a full recap see my post here: [warning it's long as I recap each turn]http://yourmovegames.com/forum/index.php/topic,690.0.html
We also played a few games of Hill 218. He liked the quickness of hill 218 but didn't seem to overly impressed.
With battleground we had a few hiccups along the way with some of the more advanced rules but all in all we both enjoyed the game and he said he would def give it another shot now that he knows the rules as I had opted to take the approach of explaining the basics before we started then explain the details as they came up. Although this does put your opponent at a disadvantage it does help to reduce the rules overload for someone learning this game for the first time.
