I'm playing the latest version of DA, and am having trouble experiencing any mega events (assuming I'm right in what I perceive to be a mega-event). I've had galactic events that have occorred in my games, such as an increase in all population rates, or a wave of Xenophobia, or a boost to tourism income, but I had all these back with DL anyway. What about the real mega-events people refer to on the forums, that have a massive impact on the game and force you to adapt to them?
I've played through 4 games now (2 completely, 1 until I'd almost won where I stopped since it was getting boring just going through the motions of training transports, waiting for my pop to grow back up, sending them off, and repeating, and my current one where I'm probably about half-way through atm), yet in none of them have I had any event other than the aforementioned ones. Mega-events is checked in all my games, and I've used a variety of strategies - with one game I relied on starbases and slowly advancing sector by sector. Another I launched an immediate attack on the strongest player and advanced my tech via conquests so I could continually build+expand. A third one I've just sat back doing nothing but research with a non-existant military until an AI finally declared war on me (whereupon I produced a super-battleship with tailored defences that wiped out all their nearby fleets). 3 of my games are on masochistic, 1 on suicidal (with the ones that I completed being a masochistic and a suicidal), and I've played with slightly different settings as well (e.g. tiny map with suicidal, small+medium+tiny with maso, normal and slow tech rates, etc.)
Is there any way I can increase my likelihood of getting a mega-event? Is a mega-event guaranteed in a game, or is it more like there's a tiny % chance of it occurring on any 1 turn, meaning that there's therefore a chance you can go countless games without ever experiencing one? Does luck play any role with mega-events and their chance of occuring (since on several of my games I've had +50% luck due to the weapon bonus it gives)?
Thanks in advance for any tips+clarifications
