I like rain to happen naturally, not force it (though I do it from time to time). Really adds thrill and makes you think hard and fast.
Just yesterday I booted up F1 2019 after I repaired the shifters on my wheel, so I hadn't raced in a while. 25% race at Hockenheim, sim damage. It's raining a bit and I start in inters, as everyone. Because I'm dumb like that I spin at turn 2, drop to last and start driving the hell out of the car.
Good ol' Jeff tells me the rain will stop in around 5 minutes and after a couple of laps I do notice a line forming. I consider pitting, Jeff says no, inters are fastest, but as I finally get within striking distance of the pack, I disagree, so I dive into the pits for softs.
First lap is super tense and I screw up the 1st sector. But sectors 2 and 3 come green. The very next lap, everyone is in the pits and I shoot up to 12th. Could've been higher if I hadn't messed up the out lap.
After a while, the sun is shining. But that also meant the tyres were degrading. Jeff calls me in, I see the tyres are at around 50% usage and I have around 5 laps left so I ignore it. In the last 3 laps the tyres really go off a cliff and I start understeering like crazy. I'm 7th after a couple of overtakes, but I lose one position to Bottas, apparently caught out by the weather as well.
That's when the two most intense laps I've had in that game begin, fending off Sainz and Perez, to finally cross the line in 8th. I was exhausted. And all that was due to the dynamic weather system in the game.
So yes, weather to me is always a great addition to any title.
