Overpriced assets?

I feel your pain but also see logic in the cost because it took me over an hour to learn how to make a very very low quality vehicle and that’s with out staticmeshs, rigged, animation, wheels (lmao) that move and not knowing how to import a blender file sucks lol. But I would like to see devs put in either trials to where you can try out the assets before buying, demos where you can try maybe one of the assets or my favorite free until you actually make and produce a game. So for instance, you really like an asset so you download it and begin using right away, well in order to produce or “BUILD” the game to a complete state you must purchase the asset or it won’t build your game to be produced. IDK if that’s possible but sound like a great idea for people like me with no future in actually producing a game but want to see what I can do with it, so who knows in future maybe I learn enough to actually produce a working game that I can be paid for then I would buy the asset because I know I’m not just throwing money out of the window. Right now even with marketplace content you still have to know so much about what your doing before you can actually implement just any asset into a game and expect it to be like a final game product, no it doesn’t work like that. So why not just free until you go to build the playable game the assets that are not “FREE” say you must buy product before building the game with the assets features in them.
