It’s something that less experienced devs usually tend to do.
Also remember that these devs are usually are not even in their twenties, and most of them suffer from Dunning Kruger. It’s not me being a douche, but something I witnessed over the past few years in the “internet community”, not only devs, all kind of people.
I’m 32 years old, I had my “lets make the best game ever” moments, but once you understand the huge amount of work it takes to make something of quality, you understand that:
1- you go the Minecraft route (7+ years IIRC of development of a one man team).
2- you start making simple games first. Simple doesn’t mean cheap and awful. You can develop polished, well defined and short games. Don’t confuse both.
But… yeah, I agree with OP.
Anyway, I’m learning UE4 with those amazingly well made tutorials, and I’m enjoying the ride quite a bit. Actually, lately I’m using UE4 a a game instead of a tool, how cool is that…
In my particular case, I got a well defined idea in mind, and the artistic aspect is doable, so, in theory, in 1-1.5 years of using my free time I expect to have something cool out there. Game will be free anyways, is a hobby’s project.
