It depends really. Romans have more disipline so more people would be taught to fight and be punished for not doing something right (Ithink). But CHB is pretty laid back when it comes to that. Sure they have sword fighting and such but from what I've learned about Rome and Romans, it's really less intense then it should be. Idk, it all depends on who's fighting, previous training, if planned in advance. So I'm not really sure.

They have the same chance.
Both have qualities that give them an advantage.

...you don't even know anything about the Romans. We've only met one Roman (Jason). For all you know, the Romans could be total wimps. Not saying that they will turn out to be like that, but still...

Well the romans won once already so...

I don't know much about the romans yet....

Do u people not remember wat happened the last time they fought?

I really don't know but I would like to think that Percy always (mostly always) wins :)

Camp Half-Blood is kind of like a regular summer camp, except it has mythological creatures like harpies and pegasi, and they have weapon training. Romans were stricter and more serious about battle. They are definitely not wimps. @Klug and others who say you don't know much about the Romans: Haven't you read The Lost Hero? Jason is, yes, the only Roman demigod introduced so far, but he tells the others what they are like. Annabeth also knew, being the awesome smarticle she is. So please reread the book. And learn about Rome.

they have better strategy lol

dont pick greeks cause u like them more.....

Greeks are warriors.
Romans are soldiers.
Nuff said.
