I think this would be useful but i hope epic or the community will create a decent free content pack which includes all the common stuff you’d expect and then some.
While it’s nice you can take content from the demos it’s really not the same as having a good starter pack. I think this would help a lot of people just trying to learn or quick map creation for projects etc, also it would just be really useful in general and is kind of expected if you’re a mapper coming from other games.
