Releasing files will never destroy a community, we will only grow. Man up and deal with the fact people love to explore and test things out for their own. The fact you want to limit people on what THEY want to create is completely ignorant to the complete creative process. Yes they start with a real map, but usually make alot of drastic changes. So I wouldn't worry to much, not to mention; the server owner is what makes the server. You could have the best server engine, and map with all the files; but if you are complete idiot to your players you will get no where.
Also Printer if you want to release something, just release it; inspire on your own levels; dont ask what people want from you to be inspired. Otherwise you will constantly be running in circles! I've seen you posting about, and jumping around from multiple projects that you are working on and it doesn't seem healthy for your creativity unless it is what you enjoy. I feel you need to find what you have a passion for and work on that, if that means it is one of the projects you are offering to release, dont release it and release the others. Otherwise, post all of them and move onto something better for your time that you will actually spend more than a month or two on before jumping to something else.
This is all just my personal opinion, I am by no means telling you what to do; but from a third perspective if I was in your shoes; I would feel completely detached from who I really him due to the fact I constantly ask people for "my opinion". I know to you right now, you just want their opinion.. but if you live by someone elses opinion you make it your own as well. Which is unhealthy for your own life progress.
Key and Point: If you want to release the files (even with any bugs, because really who cares?) then RELEASE THEM! If you are just doing this for attention or to figure out what you want to do with your Open Tibia Developement life, then go for a walk outside and really thing about your life and where you spend your time.. what makes you happy. I feel you are an intelligent person, you are just looking in the wrong places to continue your creativity.
Again, all just my opinion; take care mistah!
