Either I have the worst luck, or the number of UFOs that pop up for the player to shoot down is really small. Here is a number of problem it created in my case:
1. Because I almost never intercept, I have no idea that my interceptors are out of date. I figure the ship, with a plasma cannon is enough... until one minute I need an altogether new type of ship, I stand no chance at all.
2. It creates an ellerium shortage. Since I never sell any resources that are actually required, when a deal came along for some plasma rifles, I manufactured and sold them without thinking twice(and it was over 2000 in credits!). After which, I built an ellerium power generator and bought expensive items. The result? I can't research anything, including said new ship, because I don't have the ellerium.
3. Because I'm stuck without a new ship at the ready, I had to let 2 encounters with end game UFOs go, resulting in a C grade.
Mind you, I have satellites over every continent and over every European country, this doesn't seem to boost the chances of detecting UFOs at all. It's just another point added to the list of stuff to keep in mind for the next playthrough. Research the new ship, don't accept deals where you have to manufacture a large number of weapons, even if it means a huge amount of cash.
