The price is currently not worth the product.
Of course the plugin works fine, but it is definitly not the advertised "high customization-level". I also own other WorldGenerators, that are sold on this platform. Many of them offer much more for nearly the same pricepoints.
With this generator you can roughly edit things. For some people this might be enough, for me and my survival server this was more a deathtrap with waste of money for the current moment.
After my first review the developer told me to join there discord and offer my requests into #features. Sadly this channel is closed since 3 days(My first review was from today). After that I asked in the help-channels, where the community was more making jokes about bigger critism than rather helping. The developer itself stayed cool, but havn't really got my point.
I do like this plugin, as it has different terrain-evaluation per biomes and cool biomes. But if I can't remove flowers/other things from the overlay or the layers of each biome it is not usable for a survival-server. For me it is also important, that my players can't farm hardened clay from the flows in the flower-biome. The onliest option would to disable that biome, which in the end results in non existent plains. Also editing terrain-evaluation of the biomes is currently non-existent.
For me the current plugin does not offer a "high-customization-level". The tree-Options and other sections are sometimes a maximum of two settings.
Attached is a also a config from the plugin, so that you can see, what I mean:

In my opinion this plugin had made a good start, but I was disappointed seeing the price raising, while they just implemented new biomes, that doesn't help making this world survival-friendly.
The world generated with Stratos is at the moment cool for creative-servers or people that want to build in them in creative, but I would not recommend it for survival-servers. The lack of customization is definitly missing to other generators, that are selling at the same or a lower pricepoint.
I had hoped to get better results, than with the other generators, but in the end I would say it's currently not really ready. I will stick to the other ones, as they are really more survival-friendly at the moment.
I will update my review when the developer really add features, that make it more customiazble.
