Age of Empires: The Titans is probably one of the best in the series.
AOM: The Titans is a real-time strategy game where you can control different factions such as the Egyptians, Norsemen, Greeks and Atlanteans. Instead of planning out a good attack strategy/defensive strategy on the battlefield like Medieval II: Total Wars, AOM: The Titans is a game where you build your empire, destroy your enemy and then be victorious.
The fun factor for AOM: The Titans.
AOM: The Titans fun factor is most probably the campaign's cut-scenes and cheats. You can also take time to mine your gold, chop for wood and harvest farms for food but who would do that kind of stuff? Let's talk about cheats. Cheats in the game is what makes it fun. You go on a single-player game, type in a cheat for massive amount of resources and then build up your army. You could also have plenty of Titans to destroy your enemy. Another fun factor of this game is that you can play multiplayer with loads of other people. You can join forces and build your combined empire all over the map and stuff.
Control and Gameplay.
The control system in this game is pretty simple. Hotkeys are rarely used because everything is so convenient, unless your opponent is attacking your empire, of course. Gameplay is something like Command and Conquer kind of stuff, but totally different from Medieval II: Total Wars.
Graphics.
AOM: The Titans graphics isn't that all too bad when you zoom out on the battlefield, but when it gets close (like the cut-scenes in the campaign mode), you can see that the graphics totally suck.
Conclusion.
Age of Mythology: The Titans is a great game to play. You can do it singleplayer or multiplayer, it doesn't matter because both of the modes are fun. Probably one of the best in the AOM Series because of the titans.
