If you're looking for something fresh with a solid RMT (Real Money Trading) scene, Night Crows is probably your best bet right now. I’ve been playing it on both PC and mobile, and the Unreal Engine 5 graphics are honestly impressive for a multi-platform title. The economy is heavily driven by tokenomics, so there’s plenty of room to grind if that’s your goal. If you want something a bit more traditional but still active, Albion Online is always a safe choice since the player-driven market is basically built for RMT, though the learning curve for PvP can be a bit steep. Both have huge communities right now, so you won't run out of people to trade or party up with.
