Honestly I don't like the new tech tree. First, they left out mass media, but in fairness they've replaced it (kinda) with telecommunications which is broader IRL. Second, steam power after industrialization? Are you kidding me? I don't see the logic here based IRL. Third, and this is what ires me the most, why have an atomic and information era? IRL the atomic and information ages are brief spans of time relative to the much broader Modern Era, like in games before G&K.
So basically I base my judgement of the tech tree to real life. On the plus side, they've added Drama & Poetry and Architecture.
