I've finished the first play test of my games combat engine and basic skills.  The set up was the players were on a train headed to New Jericho which was hijacked by a terrorist organization called the Daggers of Solomon.

The players had to defeat the terrorists and disarm two bombs before the train was blown up.

I had six players, four from my standard gaming group and two that I have played with off and on.

We played three sessions each approximately three and a half hours long.

Overall I am very happy with how things went.  Everyone had a good time and I got a lot of valuable feedback.  The core engine worked well and produced the effect I was shooting for.  That being said there is a lot of room for improvement.

As expected the biggest hurdle was the shear number of abilities thrown at the players.  Each of them had 5+ attacks, 16+ counters, and 8+ follow-ups.  The first round took 2 hours to get through as each player got used to what they could do and the rules.  However the players were able to catch on quickly and the second round took about 45 minutes.  Every other round lasted between 20-30 minuted depending on the number of opponents, etc.

Stunting increased the time it took to get through a round as the players would often stop to think about a stunt suggest one to another player but the increase interest in the fight and flavor it adds is more then worth it.

Some specific changes that I'm making to the system based on my observations and player input are.

Dropping the global rule where non-lethal damage would stage up to lethal if it was higher then the target's Constitution. 
In the end this was an unnecessary extra step that made spike damage much more lethal and devalued armor.  In its place I'm introducing a new weapon quality Crushing that has the same effect but is only on a small number of weapons/attacks.

Replacing lethal Brawling and Martial Arts attacks with Crushing attacks.
Lethal Brawl and MA attacks were ineffective because armor would always stage it down to non-lethal. 

Adding a new level 5 counter to each combat skill that is very effective at stopping a single attack.
The players and main NPCs need better tools to deal with the occasional attack that roll really, really well (aka spike damage).

Reworking the counter/follow-up system.
Right now some counters and follow-up of each rank are recoverable and others are not.  The problem is there are far more non-recoverable abilities then there are recoverable ones and they are (by design) always better.  This devalued the recoverable abilities and the system for recovering them.

Instead I'm going to even out the effectiveness of all counters/follow-ups of a given rank and make it so your highest rank of abilities in any skill are none recoverable but all of the abilities in the lower ranks can be recovered. So if a player had rank 4 in Firearms they could recover any of the rank 1, 2, and 3 abilities but not the rank 4 ones.

Also I am going to reduce the number of follow-ups and counters gained at each skill level by about half.  This should make it easier for players to manage the game and increase the need to recover abilities in a fight.

Limit the characters to one Extra-Action Counter and one Extra-Action Follow-up per turn.
This is primarily to keep combat moving.

This is the first time I've truly run a play test.  If anyone has any suggestions or advice for my next one I would love to hear it. 

30 minute rounds seem painful.

Have you considered imposing time limits for combat actions?

Sounds good, as long as everyone's engaged the whole time rather than waiting a half hour only to miss their attack!
