Snail Games (China) has released new information about the upcoming revenue model for Black Gold. Called "Optimal Time-Based File Save Model", players are given the opportunity to save their game progress through the use of in-game gold purchased with real world cash.
"We're focusing on giving our players choices when it comes to their gameplay experiences - they decide what premium items to pay for and whether a play session is worth saving," said Shi Hai, Founder and Chairman, Snail Games. "We decided to introduce an innovative monetization model based on player habits and overall gameplay time. Unlike a micro transaction model requiring the player to frequently shop for items, or a subscription-based model where players pay a monthly service, our model allows players to dictate their own gameplay progression."
