With the new foundations being laid down and the new work flow for artists to bring their custom content in (animations, models) being much shorter, it’ll open a whole new medium for people to express themselves in.
Custom animations in Garry’s Mod were a thing, but it was so painful to work with them - Each model had (there are player-made solutions to that) to have them compiled in explicitly, but still, the whole effort of even getting an animation to work wasn’t worth it.
I am happy to see that S&Box will let us express ourselves even more so than ever before.
I think people are wrong to compare this to Garry’s Mod 2 - I think it is paving a great foundation for a new game PLATFORM, just like Roblox.
