Umh... Yea, is this greedy? And am I allowed to?

But still its like you work months of scripting a levelediting. For no reason, how ever this is really good practice

It's not for no reason, you make maps because you like doing it, you like people playing what you created, you like the sense of achievement after conquering an entire storyline for people to play, and it's even more rewarding after putting all of your effort into it, you get good reviews, plenty of people playing your map, even let's players making videos, that alone is a reason of worth.
