Civ is not the card game "war" or a slot machine. It's a strategy game, and "derp something you can't realistically plan for helps or hurts you" does not constitute strategy. "Derp" is usually the kind of thing that removes strategy from games...I don't see how someone can possibly make the argument that skill equalization is a good thing for a strategy game...
I completely disagree. A solid strategy includes contingencies for unplanned occurances. Anyone who plans in advance, be it Civ or a IRL company's 5 year plan, without planning for contingencies should be ganked from holding a "I am a strategist" licence.
I play Diety/Marathon all the time. I have always kept not only events on, but have modded my games to increase the frequency of events drastically (10% per turn across all ages, plus most are now recurring) and always play with the Raging Barbarians setting on. Why? It is a challenge. While some games do end prematurely because of things like the Vedic Aryans, those are always the exceptions, not the rule. You shrug your shoulders and move on. Then again, I am one of those people who play for fun and the lols. Even while losing, I can have a laugh at myself. Ever seen neat squares of samurai die en massed and in place via catapults, creating a neat square graveyard of skeletons in Age of Empires 2? I have. Those samurai were mine. I laughed so hard that I could barely see the screen and at the end of the game, I gave my friend with the catapults a grinning "I'll get you back for that!" I learnt from it, and next game, I trounced his arse.
I have yet to see an event that cause you to automatically declare on your enemy (or maybe I don't remember it). The only one with a potential to do so gives you a choice, and only option 3 causes immediate war (actually, only if the enemy civ wants to declare war, which the AI does 100% of the time).
There are few events which you cannot control that will automatically kill you. Vedic Aryans is one of them but only because they turn up early. Otherwise, 4 archers is just free xp. I'd be more worried about the damned Gothic axemen, the Hunnic horse archers or the Philistine swordsmen! Bermuda Triangle is annoying, but can be mitigated. Just stop sending your troops across in one massive SoD. One of the stated aims of the creators of Civ4 is to abolish SoD as seen in previous editions of Civ. Hence, collateral damage and the like. The Bermuda Triangle is just a more extreme example of it.
If you don't like events, that is fine, but don't insinuate that other people are ******** because they play with it on, or claim that just because they wreck
your strategy, it must be a sign of anti-strategy. Maybe it is a sign of you needing to plan for contingencies more in your strategies and emerge as a better strategist.
