Could be... I like the mod because the wars at the end get so much bigger, and it takes even longer to get through the tech tree. I always aim for long, drawn out games, and this mod is great for that. It also doesn't stray very far from the original, so in most ways you don't feel like you're playing a mod at all.
I've found that playing this mod coupled with conquest, cultural (modded so you have to have 30 cities reach legendary status), and diplomatic (I always make sure I build the UN so I can usually control the votes) victory conditions turned on gives me games that last 25-30 hours in most cases.
I also changed the value for how many nukes you can use before the world, "cracks like an egg". Nothing pissed me off more than that stupid rule, so I changed it to 9999, lol. Now in my games you can nuke people back to the stone age, which is at it should be

(although in many games I make sure to pass the non-proliferation treaty, especially if I'm not the biggest civ or am a bit behind in tech)
