And if Early Access doesn't work, why have other Early Access games like Palworld worked?
It seems to me that according to a marketing expert's blog, one of the keys to success is that they last at least 10 or 15 hours.
You talk about this game? I read about it for a whole half minute and believe that your situation is not comparable.
It is like asking, why you can't cross the sea in a barrel, because barrels float and ocean liners float too and they can cross the ocean.
The floating is not the cause, it is just a helpful thing. Same as it is not the early access that gives success. Same as having a demo version gives not success. But take away the floating or the demo version, and you gonna have a hard time.
Early access is a money grab with usefull side effects. You either satisfy demand for a game that was advertised or you use it for extended beta testing and to get some money. Also, free marketing. And releasing in "early access" gives excuse to have even more bugs in a game that people would be angry about, if it were regular release. And that palworld marketed for a about three years before going early access and we talk about a game with a budget of around 10 million dollars.
The play time is another such thing. Just because you inflate your play time to 15 hours does not make a game successful. But on the other hand, very short games are deemed by some players not worth the purchase. But it depends a lot on the genre. For a crafting game, 15 hours is a bit on the low end. Those can easily have 100+ hours of play time. And if you do it wrong, people might detest the grinding.
Now, there is a bit of wisdom in the play time. But you need to view it backwards. If you managed to make a game that people want to play for 10+ hours, that is probably a good game and might have commerical success. So if you only look at the commercially successful games, you will notice that there are many games with a play time of 10-20 hours - and might jump to the conclusion that the play time is a cause. It is not. It is an effect or maybe only a side effect. Because you do not take into account all the other games that have this play time and are unsuccessful.
And that is my conclusion about all this. There is survivor bias at work. We notice the games that are successful and see things they have in common, but that statistic will not tell us, what is cause, what is effect, what is correlation. And the marketing budget is often forgotten.
You Know? For every long paragraph you make, you are right. The success of the game doesn't always come from investing a lot in marketing or its quality, but in an unpredictable way and it is the consumer who decides to buy or not, among other factors.
Many so-called marketing experts or even the developers themselves have the mistaken idea that to be successful, you have to superficially follow trends without understanding them.
Before moving it to Early Access, it was only the alpha and beta demos with free donations, but I realize that even with that model it didn't work much. All this boils down to is that it's not the kind of game that people want?
I may not be right, but I try to argue soundly. The thing with the demo version I advised for, was because of observation. I noticed games with paid only content having less ratings and followers and comments than pay what you want games. This still might be a fluke, because of what games I did browse. Maybe there are paid only games that fare better, because they are paid.
Having success as an indie game developer is a bit like having success as an indie musician/singer. There are just so many people trying it. It is hard. Even if you do everything "correct", you might still not have success and frustratingly see projects that did many things wrong yet still are more successful.
Oh, and you observed first hand what a demo version could have as an effect. People posted videos on youtube while playing your demo version. Maybe you got some followers due to that.
