So Cubecraft went for the safe route (the games that already were popular) instead of taking the risk of trying to update other games to make them popular too.
Going the "safe route" is not necessarily a bad thing.
There's a lot going around about potential, but potential doesn't mean anything if people don't enjoy the core game play of the game itself. What is potential in the first place? Well taking the literal definition, it's:
In this context, it's adding new features (e.g. world events, kits, abilities). But looking at the updates aimed at various games such as Survival Games or Battle Zone, they didn't in the end managed to keep the games alive for long (though Battle Zone did have a nice run, but it was practically impossible for a game to start after peak hours). So what does this mean? Are the updates not the "right" updates, or are people simply not enjoying playing these games?
