Good thing would be to add custom map editor. Some people might want to make some irl tracks with roads like on for ex.: Westhill or Blackwood which isn't avaliable on Layouts
Small indy team of devs (2 devs), released in 2004 (early prototypes in 2002ish), MMO/online, no p2w stuff, almost free to play (monthly sub), similar graphics and concept, low system reqs, gradual implementation of new stuff with formula that didn't change much https://www.vendetta-online.com/
Basically, if LFS devs were more interested in space simulator back in 2002, they would have designed it the way Vendetta Online exists now.
Even if it's not available for multiplayer, I'd love to be able to build custom map circuits, though I'm not sure what format the maps are built in and I don't imagine they are obj files that I can construct in blender.
