I've been reading up on the lore, as I do with most games I play and I like it so far. It's nothing special or anything but the main reason it's good is that it actually seems feasible. It's all well thought out and realistic. It makes sense how certain events are connected to each other and so far haven't really noticed any inconsistencies (even though they have multiple writers).
What I don't like is that the lore is kind off all over the place on their website and pretty hard to get into, because they've been releasing it in bits and not necessarily in chronological order or anything. The timeline website helps sort it out though but I think it hasn't been updated in a while.
