BRG II mod was great - fun and challenging. BRG III is polished and updated - it's just brilliant. The tension with which the campaign goes (WRE), the economic situation... It's all so realistic, yet so much fun. This mod has really gone a loong way since IBFD and I personally like it more (not trying to bash mommy).
Now, some observations:
-The starting armies have been changed. Good idea.
-Rome is much more of a challenge to play with, like it says in the info. Roman (only their?) unit costs/upkeep changed dramatically. I can now barely keep things together. Even got my butt kicked by the Vandals at Mariana and lost Ricimer.
Maybe a more defensive approach is in order until I get the economy running.
-All previously 0-turn units except Foederaty Infantry (only one type) are now 1-turn. Interesting decision. Means slower recruitment (which is realistic) and makes battles more important, IMO. (You can't pump out a new army right after you lost one)
-Graphics: The new portraits are stunning! Really love the more 'barbarized' look!
-Domain of Soissons - Finally in the game! They seem rebalanced and hit Tolosa the first years of my new campaign! Never done that in previous versions.
-New currency - solidus. I doubt denarii are appropriate for the time period. Nice.
EDIT: Forgot one thing I wanted to ask. Pedites Romanii have the same upkeep as before. (around 1000) They have appr. the same stats as, say, Limitanei, which have an upkeep of around 1500. Is that intentional, to help the Roman players have a less expensive 'true Roman' troop?
If I have questions or further notes I'll post them
+ Rep 
I'm first, and its great!
)I'm not satisfied with yet. I do have something in place that will require a separate barracks for the Barbarians to build but it hasn't been implemented in the mod yet...will be in the next upgrade
