I've played the game in its table top form since the early 90's. This is an excellent duplication of that game.
You can't judge it against modern computer games, because those try to keep everybody happy. Blood Bowl may break up friendships, set brother against brother, sister against sister and generally ♥♥♥♥ off everybody at some point in time. Because it honestly does not care about your feelings. And that's why you know it's a true to life replication of the original Blood Bowl experience.
If you think the game is cheating to beat you, you haven't paid attention to the odds. The RNG is not broken. I've seen people smash real world dice with a hammer, or melt them into puddles, for rolling triple skulls, TWICE in a row. Do not imagine that it's impossible for the computer to roll the exact same way on that game winning play.
A lot of people say that the game is bugged. I've watched a lot of games on YouTube where somebody has blamed a bug for a play not going the way it's supposed to (in their head) or for the "wrong" dice being rolled. Haven't seen one yet where that person didn't just miss one of the rules, or spot the goblin marking their treeman, ruining the assist for that ever so crucial extra die on a block.
Like the original game, there are problems. Team progression (trying to build them up, whilst minimising damage costs and replacement players) can be very difficult to manage, sometimes not even worth it. But that's not the real fun of the game. The real fun is in taking on your friends in blood-thirsty combat and beating them with a humiliating three point lead. It's in screaming that "DWARVES IS CHEATING!" and your opponent smiling and saying, "yes. Dwarves is," and then proceeding to wipe the field with your squishy elf team.
It's a game of playing the odds and knowing that even when you DO play the odds, they're only odds, not certainties.
And if you ever anger Nuffle, RNGsus help you.
