I think the only mods that add value are ones that add interactivity like they SHOULD have had. Like it’s super lame the T-Rex in JP doesn’t do anything, when the DE one was awesome.

I’m not super familiar with those mods but I know there are really cool ones like the buzz saw for TOM and some plane mods for IJ. Things that make it more fun to shoot for add value and actually do something, not those that are just goofy dolls and action figures.

In short, most “Mods” don’t. Utilitarian mods with purpose do.
