TBH, I hope they still have quite a bit of stuff in the pipeline. The game is still extremely elementary. Missions are repetitive, bounty hunting while fun lacks real substance, exploration is cool for sight seeing but otherwise not particularly entertaining or engaging for the average player who isnt interested in that, let alone worth while. And most importantly theres no real motivation for social interaction since anything in the game can be done (and frequently better) by a single person. Most "online" games like Elite is aiming to be live and die by their community. Good channels of social interaction vastly improve the players experience, and many of which are frequently driven by teaming up to accomplish huge goals that are otherwise insurmountable alone which will keep people coming back again and again day after day. However, theres a huge stopper right now from making that happen...
Most of a players motivation is driven exclusively towards reaping in money to upgrade their ship. Anything that impedes that is on a whole undesirable. Two bounty hunters cant cooperatively work together to take down a particularly dangerous bounty (not like anything short of an anaconda qualifies) since one player will get screwed while the other gets all the cash. Two players mining together can end up being more of a detriment than a boon, since good worth while deposits of resources are rare, and a player will want to scoop all that up for themselves. You cant have 1 person scoop the ore while the other mines since you cant split money.
Theres also no trading or industry. Theres no crafting system (making anything less than the most profitable ores worthless to mine) and I dont think Frontier has any intention of adding one either.
The only instance I can think of for players to team up and have all parties actively gain something in return for it, is piracy, since a tag team or trio of players can work together with significantly reduced risk to themselves to crack the cargo holds of large targets. Since something like a Lakon can easily drop more cargo than a single cobra can pick up, everybody wins. Soon as the players start scaling up though, this benefit quickly diminishes.
Which sucks.
Piracy can be a fun and interesting aspect of the game, for sure. But being that its the only real source of player interaction, it really means that outside of cooperative piracy ops, all other player interactions are negative or undesired, including the PVP that piracy will generate (from the traders perspective, this is nothing short of "getting screwed". People have little reason to be anything other than bitter or at the very least suspicious when another player shows up, because it can very well mean that theyre negatively impacting their own profit margins. Whether thats another miner showing up to scoop your ore debris, a bounty hunter competing with you for kills, another explorer who could turn in those newly discovered astrological scans or even rival traders who encroaching on your trade routs.
I'm sure I'll get neg repped for pointing all this out by some optimists who can think of some obscure scenarios that at least dont negatively impact the parties involved, but the fact of the matter is that the average gamer is very self concerned. If an interaction doesnt benefit them, or at least seem immediately appealing, they arnt likely to do it.
Its my genuine hope that Frontier's next step now that all the groundwork (which imo is very solid) is in place, that they'll start developing the infrastructure to support player and social interaction in a positive, beneficial way, and create content that draws players in and actually WANT to be together. Its in my honest opinion that good and worth while cooperative and group content will be the strongest lure to draw players into open play.
