Not really. They defeat the Manas by hitting and kicking them and they even "slaughter" a Mana-Ko (I think that's its name). In MNOG the Manas are defeated by destroying the towers, which shuts down their energy source. It's not quite the same. Then again, we may both be reading too far into things.
Also, keep in mind that if the 9/11 theory about the cancellation of the game is indeed true, it's no wonder Templar would picture the Manas fight in a less brutal way.
The brutality is basically the same in both versions - the Kaita wack Manas about with their weapons. The MNOLG is arguably more brutal in Wairuha taking a few blows and being briefly knocked out.
