If you find the AI to be to much of a push over, you should use ironman rules for yourself to make the game more challenging and rewarding.

Most of the battles I fight involve flanking the enemy and hiting them from the sides and rear resulting in mass rout. I spend more time in every battle chasing routers than I do fighting the enemy. Recently I have limited my use of flanking and it has made the battles last much longer and much more enjoyable. You will get higher casualties, but the battles will be more fun.

The Broken Cresent Mod adds to the difficulty by adding an area of recruitment system where you can only recruit tough and elite units around your home provices. Not being able to retrain and reinforce your armies without marching armies from your homelands can be a great challenge.

There are also other mods that add alot of cool features to keep the game interesting. Lands to Conquer gives enormous amounts of money to the AI to make it field some tough stacks. Deus Lo Vult adds an RPG element that makes it more fun to develop your generals. Stainless Steel adds a huge map with many playable factions and with a good AI.

MTW2 will remain a great game so long as it remains challenging and rewarding for the player. The more experianced player may find some bugs here and there, but none of them should be gamebreakers for the casual player. Although I would love to see another patch, I think that CA has done a good job of providing support for their product. Whats really awsome is that CA allows people to mod the game as much as they do. If your a more experianced player and are looking for a greater challenge try some mods.
