Well, yes and no. It all depends what kind of player you are.
For people who roleplay on this game, new groups and plots can strengthen their literacy skills.
However, in terms of animal behavior... definitely not. Most of the pack/pride/clan roleplays aren't exactly realistic. Even most of the claimed realistic roleplays aren't really accurate at all. (That's not to say they're bad groups, they just aren't dead on realistic with behavior and such.)
So, overall, I wouldn't call it educational. Yes, you may learn some stuff, but it can be unpredictable on what you experience in terms of realism, and isn't really enough to be considered as educational.
If Feral Heart was a educational game, then it would be more similar to WolfQuest -- but more stricture on the forums and games; you basically don't have freedom. Then again, you are able to learn a few quite interesting things there. However, for FeralHeart, is different. Yes, animals may sound kinda educational but isn't really. Here, theres more of a exploring game and chatting. You're able to do and make whatever you want, without it being a SPAM. I'm serious. Personally, I don't see Feral Heart as educational as WolfQuest, but more for teens who are older than thirteen.
Also, if Feral Heart was educational, then it would be strict with *harsh* laws and rules. But then again, it's not. It's more of a...get away game with you can enchant and inherit your skills and creative. ;) But just think about it, would really happen if it was educational? Eh.
And even if it was an useful and educated game, just look at the chat. Look at how the users uses them. You only see curses and randomness. Now, that's not professional. Just immaturity.
