Computers have never been any good at random generation. Any gamer knows the wrath of the RNG gods.
Missing a 95% chance 4 times in a row? Highly improbable in real life, but perfectly ordinary for a computer.
Many games are utterly ruined by this.
It is not a strategy game if the only winning strategy involves getting lucky.
And it's so simple to fix. It doesn't need to be random, it just needs to be unpredictable. There are many ways to achieve this. I take random values from diminishing pool. An array that holds all outcomes and removes each as it gets used. This results in a random order, but equal distribution.
A good example of what I mean is the game Warbanners. It has the potential to be a fantastic game, but the rng has the ability to one-shot kill any unit at any time. Nothing you can do to stop it.
You can have a battle where you make all the right moves, but watch your most powerful units get killed by battered weaker units.
WTF?!
If I want to get fucked in ways beyond my control, I'll go outside. I dwell in a basement playing games so that I can have some control.
I don't mind a game that punishes me for making mistakes. I love a challenge. But the 'Surprise, you're dead' game mechanic has always been taught as a design flaw. It's basic game design 101. Yet can be found in many alleged 'strategy' games.
This is why I haven't finished Xenonauts. It is an XCOM spinoff set in the 60s. Most of the ground missions have the same ending where you have to get inside the alien ship and clear the last few enemies out. You level up your soldiers, give them the best gear and position them in the most optimal way possible, only to miss two shots with a 3% chance of failure and then have your best soldiers one-shotted. Good luck replacing those soldiers you spent half the game leveling up. I'm convinced there is no way to finish the game without reverting back to earlier saves a couple of times to stop the bullshit RNG from killing you.
It is also incredibly annoying in speedrunning too. Ocarina of Time 100% is probably the best example. You play two hours of the run and then come to a part where you have a 10% chance to get the item you need every time you attempt to get it. Every attempt takes 15 seconds. Someone actually went 104 tries without getting it once.
