What's Your Favorite Mod?

I've been enjoying VI, but I'm considering getting a mod for it...I was just wondering what everyone's favorite mod is and why. I've been thinking about the "Viking And Heretics" (?) one or the one that was called an AOE/VI cross-over (I can't remember it's name. ~:confused: ). Although, I might choose something else if anyone can make a good enough case for it. I was also wondering, do any of the mods have naval battles that can be fought like the land ones? I just find dropping ships on top of an enemy stack to be kind of boring to me. :disappointed:

Before I begin, this is a rather dangerous subject. People tend to focus on the bad sides of a mod. Which offends makers and supporters of the mod in question. Which results in flaming and before you know it the thread is closed.

SO EVERYONE: ONLY GIVE COMMENT IN A POLITE, CONSTRUCTIVE WAY!

About the mods you mentioned: I never heard of the Viking and heretic' mod. The other mod is called the Zarax-mini mod.
Some of the mods I played: XL mod, BKB's Super Mod, HTW, NTW and MedMod version 3.xx

I hugely enjoyed both XL and BKB's mod. They both add new factions and units, a modified map and 'some' rebalancing.
The other mod I played less, not because they where bad, I just wasn't 'in' to them. But MedMod 4 is almost complete so I will definitely try it!

I would recomment BKB's Super Mod. Tons of new units, and improved AI and gameplay.

Also, the XL mod is good. ~:)

As for mods in construction, I would recomment the MedMod4 and my mod, Byzantium TW. ~:)
