I've run into the same hope-crushing fleets at the start while drifting in hyperspace. Your flagship is usually able to make a hasty retreat, but your escorts tend to get overtaken. Retreating from the battle doesn't allow you a chance to zip away, as you're still drifting without fuel. If you're particularly unlucky (like I was), there's enough time for a second hostile fleet to swoop in and engage. Lady Luck is a fickle mistress. Chance dictates whether or not you make it to the nearest system with your fleet intact.
There's multiple sides to this. On one hand, you're gifted a few ships and set free in the universe, only to be greeted by the biggest, baddest bullies in town, who break your toys and send you limping home. Whatever cash you'd hoped to get selling your extra ships is a distant dream, a burning hulk in hyperspace. It's a rough start that you had no control over, and it feels a little punishing.
On the other hand, you're offered a brutal introduction to what really is a challenging mod. It's fitting, and it certainly sets the tone. Your greatest fears realized, you find yourself stranded in space. As reality sets in, you discover that you're a small fish in a big pond. Full of hungry fish. Schools of them. If you survive—and only if— you'll have to scrap it out just to get your next meal. Every supply will count. Nothing will come for free. Your hard-earned capital will only buy you so much, and even when you've built up a formidable fleet of your own you'll be reminded every step of the way that the miscalculation of resources comes with a hefty price.
Nothing like a series of grisly endings to give a success story a little context.
