CMBB out does CMBO in so many ways.
For a start the visuals and effects are much cooler and more realistic. ShockwaveShmokwave ...ever seen an explosion like the ones depicted in CMBO? (Except Nuclear)
No more cartoony style graphics = greater imersion.
Infantry react better to incoming fire.
No more dare I say it...gamey infantry tactics.
you really learn to look after your infantry forces. Use them badly they will be wiped out, use proper inf tactics and you have a powereful tactial force.
In CMBO the only reason to buy mgs was to eventually wear down your enemy with casualtys.
Mgs are now true assets on the battlefield eg. supression, slowing enemy advance, area denial and of course, total slaughter.
The fog of war is far better making ambushes a very viable tactic, especialy at guns. Also lets at guns to be used ofensively.
Artillery needs los to be effective
No more fire and forget CMBO style of arty spotting.
Due to the previous two factors, AT/inf guns survival rate has dramatically increased.
I used to to think how much I would hate to serve with an at gun battery in real life...eg suicide.
A greatly improved armour model makes tank battles way more interesting and realistic.
Doodads need I say more?
Vastly improved sound overall.
CMBB excels over battlefronts previous effort in so many was it is impossible to list them all.
There is no way I could go back to CMBO, athough a very fine game when released.
After I played the demo I couldnt go back and had to order CMBB even though I was still playing CMBO at the time of the demo release.
People my find CMBB compared to CMBO very unforgiving....that is true as it was in real life.
I can only hope Battlefront continue to strive for total realism in the future.
