Depends, building good games that establish goodwill and a strong franchise will make you more money in the end than the quick pump and dump mobile game candy crush bullshit.
The difference is that the mobile game model can exist perpetually in a state of pump and dump because the platform of mobile is essentially purpose built to be a time waster. Consoles and PC games are intended to be an activity in themselves instead of a way to take a smoke break, the ramifications of attempting to convert the standard videogame model to the pump and dump model has been successful depending on your definition.
Sure we’ve established that whales exist in every market and some people will buy every MTX they can even if it’s CoD or whatever, but we’ve also seen people who used to spend a considerable amount of money on games stop doing so, because the market doesn’t cater to their preferences. That’s the point Larian is making, you can create a true fan base with their model, you can only create addicts with the pump and dump model.
It’s almost like a few other games that are hugely popular got released and initial launch numbers never stay that high regardless as the novelty wears off and only the really committed players come back regularly.
