A lot of what I've seen so far very much fits into the Fortnite art-style still but that's no surprise considering it's literally called Unreal Editor for Fortnite. All the technical stuff is very impressive and way beyond what Forge can do. Didn't know about people being able to make and publish their own assets into the store though...So that should change the look overtime.
Assets have nothing to do with feel, all of these creations so far still have a Fortnite feel in movement, gunplay, etc. Because it's an editor for Fortnite and I don't think that will change. So I disagree that people could recreate Halo in it...You won't have the art-style, feel, gunplay, movement, enemies, characters, story, weapons, etc. Lol. The most they can do is make it look a little like Halo assets wise but get too close and Epic will seemingly ban you.
I know kids play Fortnite, I just think you're underestimating the mass appeal of Roblox amongst kids, it'll be fine.
Ryuu did you watch the presentation. Just the 3 different demos were totally different. Now the character was still a fortnite character but everything else like the Fable looking level with the dragon, the COD like level, one fighting this robot and the last was more around a spooky setting. Each one show a huge diversity from the assets of Fortnite.
Character wise that probably takes a lot more time but nothing stops anyone from creating brand new characters and animation but key framing stuff is very time consuming. The fact that you can use your own phone to to capture video of yourself and then have it keyframe your animation into the meta humans as we seen with Ninja Theory. Yes now the character are using Fortnite assets but they are not limited to fortnite assets which is what I am saying. You should know giving the community the tools they will expand way beyond fortnite assets in probably less than a year.
I am not underestimating Roblox appeal among kids, I have kids. My son and his friends use to spend a lot of time in Roblox and I use to ask him why is he playing that crap looking game. Now he is in his teens and playing a lot of fortnite. All those kids move up form Roblox to Fortnite and now they get to play all the crappy games they use to love in Roblox in Fortnite. Trust me, when the creators move to Fortnite so will the kids.
