As I stated in another thread, after some 90 minutes of play, and perhaps 50 turns into a game, I am liking what I am seeing, very much ! (Also, I don't consider the game to be particularly buggy up to this point.)
I have just one minor suggestion, so far. To unlock Level 5 heros, the game suggests that you have to research: "Recruiting". However, on the Technology tree, the actual Tech is identified as: "Heros". (It took me a while to find that.) There is plenty of space in the Tech tree for a longer title, and I suggest the Tech actually be entitled: "Recruiting Heros".
