You just lost the argument. Mirite?
No it doesn't. Your view is entirely subjective. I have played the game for 18 months now. I wouldn't have done that if it lacked depth. It is plenty deep you just need to understand what Elite is and how to find the depth.
Most people who seem to be missing this 'depth' look like they just dip their toes in to the water and claim to have experienced everything. That is their loss as after 700 hours of playing I still haven't found the bottom.
A game doesn't have to have depth to be enjoyable, which is evidenced by the fact that you enjoy Elite Dangerous, since it has little depth. DOOM doesn't have any depth but is an enjoyable game to some. In all fairness, I suspect combat has gotten a bit of depth, if they did actually fix shield cells and powerplant sniping, since it opens up more viable options for combat than "beefy shields and lasers", although they still need to fix missiles. Every other aspect is either broken or shallow as all be damned though.
But for the record, I *have* experienced everything. Because when you've gone into the black, doing it again is only an aesthetic experience. Trading is still a cr/h youtube vomit fest. Mining may have become less tedious somehow, and if it did I might pick it up again, but it's not deep by any means. Pirating is broken. Smuggling is basically easy mode delivery service. And what are the rewards for all this? Credits and more credits. Woooooo.
Depth seems to be a constant thing people tend to misunderstand. I'll see what I can do to put something together to help explain.
If you could make an objective post, pointing out which parts of Elite possess or lack depth, you'd be a cool dude.
