I'm seeing an awful lot of 'wouldn't happen' and not a lot of 'would happen'. Admittedly, without a single superpower to unify and disseminate culture and technology , things don't look as shiny as the Great Republic. But my point is, Is there the chance that another world power might emerge from an unsuspected source?
A new empire might form in Spain, or something in the region breaking off from Carthage, becoming even greater than Rome or Carthage would be.
Persia, Egypt and Greece would be vying for a lot of power in the east while this new power arose out of Spain, perhaps.
You've got all these barbarians running around beating up civilisations in Europe, of course, but those barbarians inevitably learn a thing or two from their victims - or their victims become stronger. Don't underestimate technology or discipline in military matters. Either way, central Europe (Greater Poland? I know, no such thing but it's the general area) would likely become a smelting pot of cultures and maybe have some interesting results...
You need fortifiable areas for that to take effect - Spain (Iberia), or France (if someone managed to unite the entire region ala Charlemagne) - most likely. England is a bit out of the way and Poland is just going to get ovverrun time and time again.
Italy was like this too, of course, and thus we had the Roman Empire - but in this scenario, Rome didn't-quite-make it as a -true- power... So something further west comes into being say, around 100 BCE.
Around 500BC you had Buddha and Confucius, by the way. There's a couple of influential fellows.
Persia is quite the buffer for Buddhism, and it's not exactly a militant religion at its core. It still didn't displace Hinduism...
Finally, what really happens if someone from the West contacts the Ultimate West (America)? You're looking at the Mayan civilisation in the 300-800AD period, as the undisputable highlight of the continent; they had warrior kings and an almost Babylonian structure to their civilisation (from the brief notes I've read so far). About the only thing they were missing was the wheel and big ships, and if someone pulled up off the coast in a galley I'm sure they'd be influenced. If trade started up, a Mayan sea power would be almost inevitable, thus no rise of the Toltecs, and thus no rise of the Aztecs. Further south, Andean civilisation wasn't particularly united or advanced - the Inca only came onto the scene in the 11th century.
The Incas were born out of several other civilizations from this area including an apparently important 'Lake Titicaca civilization'...
But this, also, seems plausible.
I see Carthaginian explorers starting trade with the rich Mayan agriculturalists, and a reinvigorated Mayan civilisation expanding across the Americas. Alternatively, Carthage decides to invade the land of these savages, but needs to cover themselves against all the other Mediterranean powers (incidentally, the historical atlas I have lists the Mediterranean as the Mare Internum in 200AD). To facilitate this, some sort of Grand Alliance sends a force of mercenaries or excerpted legions from every Mare Internumic power over on Carthaginian ships and divides up the Americas (assuming they win the battles, and Europeans have advances like bows and chariots and metallurgy and elephants on their side). I don't think Carthage could do it on their own...
Carthage is suffering from a dearth of resources, someone is going to usurp its power.
PS: What's the lingua franca of the period? The 'trade tongue' that everyone should know? Today it's English, a few centuries ago it was French (hence the phrase), even further back it was Latin - but without the Roman Republic conquering Europe, someone else would take center stage, probably the Greeks - their habit of colonising everything in sight combined with their arcane prowess in this model would make them highly in demand and welcome everywhere, although Carthaginian merchants would have a chance at becoming well-known too. Perhaps scholars speak Greek and merchants speak Carthagese (?) and nobles speak both?
Perhaps some derivative of what the Cathegians spoke, - Greek will remain an important language for some time.
