I can't believe people can think they've made something awesome when they have obviously just pieced together cheaply made assets that others have made, whether they exist on the Unity store or elsewhere.
It's one thing to download systems that make coding easier. Coding is hard and downloading a menu system or an RPG chat system because you don't have the time to code it yourself is fine in my eyes, although very limiting. Even buying models on occasion is fine, but maps... Not sure. They are pretty integral to the flow of a game and using other peoples assets in that way is not only lazy but you are obviously not putting game play first. If you had them made for the game then that is a different thing altogether obviously.
I started making a game in unity.

Very basic stuff and It may not look like a AAA game but it wouldn't bring the same kind of hatred from people like Jim because despite it's obvious amateurishness, it doesn't look like a cash grab.
If you're making a game you need to have a piece of you in it. It's a creative medium. At least one part of it needs to be your own work. Making a generic (don't like that word much but it applies) FPS with re-used assets is not gonna fly with anyone that has any willingness to critique the games they play.
Edit: I didn't actually link that video because of the self promo rule but Neogaf did it anyway and I cant get rid of the URL tags?? I've been banned for that previously and would rather not get a perma for repeating it :/. The game doesn't exist in any monetary way though and probably won't for many years (if ever, if we are going to be honest) so hopefully it's ok. Just meant to show proof of an understanding of game making.
