EVE Online players who habitually 'ghost train' their alts on inactive accounts are about to be given a wake-up call. The myriad options that a player can take in the sandbox game means that training up specialized alts is a common practice. The time-based skill training system in EVE means that higher ranked skills can take well over a month to train to their maximum of level five. When creating a carrier or mothership alt, for example, it's typical to simply, well, not pay $15 for a month when you're not actually playing on that character while your skill training progresses.
This isn't limited to capital ship alts though. Many players unsubscribe after queuing up a long skill and resub once skill training is complete. This is how it's always been in the game (at least since this writer began playing), and by all indications is something CCP Games has been well aware of. Those days, as confirmed in today's announcement from CCP, are over.
