This game is only fun when you are doing good. Sadly, most of the time you won't be doing good.
Lets start with the voice acting. Its pretty bad. The main character Agrippa, who is a freakin brute, has the voice of a girl and sound waaaaaaaaaay to dramatic. The second main character Octavianous, who you sneak around with, sounds like the character Robin from the cartoon series "Teen Titans".
Other characters aren't very bad but sometimes they can get a bit boring and weird.
The fighting is cool, but the missions throughout the Gladiatorial games get repetetive. Boss batles aren't even fun. They are just annoying. They make you ask this question; "why does this guy get a freakin sweet and mighty weopon while I just get this stupid dinky little thing. A lot of the parts get to hard to the point where you just want to destroy your PS2. But when all of these annoyances aren't happening, it can be a lot of fun.
The stealth isn't to bad. But you've seen it all before. The game could be called METAL GEAR TOGA. You run around in the same areas avoiding the same guards, stealing clothes. You have to wonder though, how is it that Octaviounas has a map of every location that tells him where items are and the position guards are? It must be magic. You collect coins to buy things for your room, but doing this is absolutely useless.
This game is like Metal Gear Solid, Hitman, and God of War combined.
Its pretty good. not exellent though.
