Well one of my favorite games Rome total war, made by Totalwar isn't the most popular and new game out there, but it is still immensely fun for people who just want to have a crap-load of troops attack another crap-load of troops online or off... and it's got all the amazing civilizations such as: Greeks, Macedon (same thing as greeks but just has such a different garrison ( DON'T SAY IT ISN'T GREEK!!!), Rome's 3 main families (Julii, Scipii, and Brutii) and the senate, Carthage, Gaul, Britannia, Seleucids, Egyptians, Pontus, Scythians, Parthia, Armenia, etc.
another great game by Total War is the expansion pack for rome... Barbarian Invasion... which i think is tied for the best game EVER along with warhammer 40,000 dawn of war: dark crusade. you have the Eastern Roman Empire (Byzantines), Western roman empire, both of the goths (visi, and the astro), huns, saxons, romano britans or something along that line, eastern and western roman empire's rebels, but this time have the exact same units as the original, and are the same strength, unlike in Rome where hte rebels are very weak. i'm not sure if this is allowed due to the fact that it didn't say anything about posting vids about games, but if it is, here are the youtube vids for the introductions for both of the games i've mentioned, and if you want, the third one is the dark crusade intro...
