EVE Online recently revealed a long term option for free-to-play characters that doesn't severely limit the potential for fun and meaningful experiences. And while there's not much similar as far as mechanics go between Star Citizen and EVE Online, I think there are some valuable lessons to be learned. EVE is a no-holds barred sandbox MMO and Star Citizen will have free-for-all PVP zones with a gradual permadeath mechanic. If there's any MMO out there that can help players prepare their outlook and attitudes for such possibilities, it's EVE Online!
For a look at my Top 10 list of what I think EVE has to offer Star Citizen players check out my article on Redacted.TV.
