Looking over what's here already here and not sure what's to come as I've started today.

A daily market that has limited number of items per player ( this allows new players to buy stuff cheap sell a little higher )

A new player chat so they can feel welcomed and supported by some admins or mods this can be time gated to 1 month (edited)

Destinations, where you are able to travel for exclusive items that can't be found in the main area

Terminology. Adjust some things that copy games like this one ( Torn ) Ched has had games closed for less. So change donation packs to something else like Premium Cigars and points to Cartel Coins this way it has no relation to torn

Donation packs, Great pricing but give a subscription offer with a bonus item for doing so along with little added bonus 

Personal shop so traders can make a name for themselves cost 200 Cartel Coins

Personal Achievements ( haven't seen any yet )

Community Events with Exclusive Rewards 

Many more things to add to the list but I am enjoying what I have seen so far and look forward to seeing what is to come
