I thought the only differences were errata and "putting the heat back into plasma" although that last one is a biggie. Correct me where I'm wrong. All 4 copies our group has are from the same print run, so I honestly don't know the difference. (also have the errata booklet from Fire, Fushion and Steel)
I thought blunt trauma only worked on flexible armour so at short range tl14 BD takes 15d6 damage. Still much better than the original 1d6. But I was wrong, however it only adds when the dice is blocked so against that tl14BD adds 8hp, thats 23-98 points of damage. That 18 hp kick from earlier would cause 2 and the kicker would take 8 damage himself.
I saw an editorial somewhere saying TNE was designed to be realistic and providing figures from gunfights showing that it is quite hard to kill someone with a gun. There is the quick kill roll aswell which might help things along.
But like most people I found it felt wrong in play. You get a headshot and everyone pretty much expects the guy to go down, no matter how often you are presented with figures explaining non lethal head injuries. Gameplay is more important that realism, so like most people I houseruled it too. Well, I houseruled it because it didn't seem realistic to take so many bullets (unless you are Cathal Brugha). Later when I read the editorial I decided I prefered it houseruled anyway.
The Initiative rules were good, I sometimes use MT to hit and damage with TNE initiative and CT morale. And the contact rules were a nice graft back into MT.
Yeah I liked the initiative rules too. Pity that the generation of the stat was so random though.
EDIT; D'oh given the title of the thread that looks too much like a defence of TNE. Instead read it to be;
Dislike;
Damage. (bullet sponge)
Determining of Initiative. (one role may gimp the guy who wanted to play a stoic, capable Marine)
As these are two big parts of an RPG and combat an important part of the vast majority of RPG's, this is a flaw.
GDW were gun nuts, so maybe there is a lesson here; decisions that are good for realism and accuracy in a topic who have interest and knowledge of may impede your ability to do what you actually set out to do. ie make a good rpg system. Maybe?
Ultimate example of this is something like pheonix command. Plenty of detail on what a bullet does, agles of attack, injury, penertration. Each realistic on its own. Add them together and it is long, drawn out, over complicated, boring instead of exciting.
