That does not feel like a phone game. Mobile is aimed towards audiences that have little interest in PC or console gaming, they just want to sit down when they have time, for like, 10 - 30 minutes on their phone and play a few rounds of candy crush. Win. And boom, had some fun, no big deal.
Also, RNG isn’t anything new. It’s in almost every game, you name it. Kingdom Hearts 2, dark souls, monster hunters, and even previous final fantasy titles had rng. It’s an element from games that add some form of difficulty to it. Is it also luck? Yup. But, without rng, items developers intend to make valuable or rare, will not become rare anymore. That’s ridiculous.
A gold bar shouldn’t be accessible to everyone and their mother, it should be gambled, kept hidden, locked away, etc. Anyways, like in the DoH forum, we can debate this all day, there will not be a conclusion or solution out of this.
