I think leaks of unfinished games shouldn’t exist because, more often than not, it ruins the game by being exposed to the public by a hacker in a situation where it’s so easy to say “it looks bad/unfinished” and get away with it. You just have to see what happened to Half-Life 2. Valve changed lots of things in Half-Life 2 because of one weirdo thought “wouldn’t be funny if I leak that?”.
I’ve heard there were tons of videos about an old unfinished version of GTA 6. I only watched 2 minutes of one 3 minutes video and that’s it. It wouldn’t be reasonable to judge it while it’s not finished, especially when we consider that we shouldn’t watch this. It’s very different from a demo, a trailer or a teaser, because these were official announcements.
I feel sorry for the developers of GTA 6 and any videogame that was leaked. Imagine you’re working very hard on something for days, weeks, months, years. And then there’s a guy who leaks it and everyone judges you because they watched stuff of an unfinished product you’re working on.
I think the people who leaks this stuff doesn’t care about the other side of game development, the people who intensely work on this type of projects.
