As a group we settled on liking almost all the proposed rule changes with only a slight adjustment to soldier units combat factors. The table also included a lot of terrain so we could test the new terrain effects on soldier units. Soldier units include peltasts, scutari and theurophoroi.
The game was fun and bloody. Phil was able to destroy a whole wing of elephants while inflicting some, but not enough return damage to the Gaul center. On the far flank Bob's cavalry command did well against Charlie and on the right I mostly demonstrated on my flank while Mike and Bob won their areas. When your team mates are rolling hot dice don't muck it up by adding in any more of your poor rolls than is absolutely required. That's my motto.
All in all it was a great time. Calling it a 'play test' doesn't do it justice. Really we played a great game with alternate rules in place to make sure they worked out, which for the most part they did beautifully.
