In PUBG there cannot be positive encounter between me and a player who is not in my group. We either fight till one of us loses the game or we pass by without interaction. Even that has costs, as hiding and crawling costs time not spent looting or getting to the circle. This isn’t because they are griefers, nor that because the game rewards killing. The key step is that the game is designed in a way that non-team members cannot help each other win.
In PvP MMOs like EVE and Albion, while theoretically we should fight, we have not only no reason to. The problem is that we have a reason not to: trading. If I’m not a miner, evicting a bunch of miners would decrease my mineral supply. I have the empty space now, but I don’t want to mine. The best course of action is to leave them to mine and trade with them.
But, but, but your alliance has miners and they would love the space and you could trade with them too. Sure, but after we won, I still have to trade with them, they won’t give me minerals for free. So I replace Adam with Betty in the belt with my time, my ship, my risk only to pay the same amount for the minerals. Bad deal. If Betty wants the belt, she’ll take it herself.
But, but, but she will help you take ratting field in return. Yes, in theory. In practice, she’ll be mining during ops. Remember when CO2 had its capital besieged in M-O and only 456 Goons shown up out of 16000? Unless the alliance leadership is extremely harsh, Betty will slack and just mine after she got her belts. The result is that people are motivated to just accept the status quo and trade for the resources.
How can it be fixed? By making out-of-group trade impossible. Not just formal trade but every kind of transaction of items or currency between groups. You can’t loot their corpse (you can destroy their loot of course), you can’t open their containers (you can destroy them too) or take anything from their structures (which you can destroy). Finally, if someone joins your group, he should be able to bring no wealth with him, just himself and his skillpoints (which become non-extractable). This would not only stop most of the RMT, but would force groups to fight: if Adam wants minerals, the only way for him is helping Betty get that belt, he can’t buy minerals from a stranger. If Betty wants currency, she must help Adam get his anoms.
Of course group sizes must be limited to prevent everyone to just pile into one group for better market, but otherwise such limitation would guarantee that groups would start fighting: because that’ll be the only way for them to get resources.
PS: PUBG is going well. Top 100 is expected in a week, then I post the guide how to become so successful in the “big thing of 2017”. You can guess, no “git gud” will be in it:
