Umberto, do you think I'm being unfair? Then I'll try to approach it from the perspective of a software developer, not your customer.
Well, at least the fan base for Prepar3d v4 / v5 is still large. Besides MSFS. What hasn't actually happened is an increase in P3D users.
But there have already been discussions in other forums about the missing features like Water and Lavratory in the Prepar3d version. Your statement on this was that they won't be available anymore, even though they've been announced for years.
I have several suggestions:
1. With so many users, you could outsource testing to a closed user group, regardless of the simulator. That way, it doesn't take up your developers' time.
2. If you develop new textures, that's one thing; they're also included in new purchases. So it's not a problem why these aren't simply included in Prepar3d, as they are today.
3. Although many flight simulator enthusiasts believe that everything should be free, I disagree. Instead of constantly providing updates, I would continue to develop the software if I were you. Free within one version, and if there are truly new features, I would create a new version. And that would be for both Prepar3d and MSFS.
Then it would be worthwhile for you to continue developing this software. I'm sure there are plenty of users who would be willing to pay an update fee for new extensions, even in Prepar3d.
In other software areas, this is absolutely common practice. Users have to get used to it. I, for one, would have no problem paying for a good update with new features to you.
Thanks anyway for the bug fix, even though I haven't been able to test it yet.
Regards Dieter
