Years and years ago I played Star Wars Galaxies. I'm old. Before it got destroyed it had one of the greatest crafting components of any MMO maybe ever--all the way from mining/hunting/scavenging for resources and components, to obtaining blueprints/schematics, to detailed specialties and sub-specialties for weapons/machinery/vehicles/homes, to merchandising and marketing. Regardless of where SWG ended up, the crafting component was fantastic at best and no worse than merely good from inception to termination. I haven't found another MMO that has anything like it and gave up on MMOs when my first kid was born about six years ago. I tried LOTRO and SWTOR and did the trials for a few others, but nothing with the depth and breadth of SWG.
My kids are school age now and I finally have some time on my hands--not infinite amounts of time, but they're pretty good now at keeping themselves occupied for an hour or so at a time with toys and books and I don't have to constantly keep them from stumbling into injury and things they're not supposed to be getting into. Is there any MMO out there now that comes close to the crafting/exploring component of SWG?
