My suggestions:
- using 3d models on icons don't work, it takes too much time to process the information. (For example I can't immediately recognize the blobish 3d model to be a research lab)
- I would say stay true to the original graphics of the boardgame but the problem is, they are terrible at conveying information as well
- best would be to change back and don't release until properly tested
Hope this isn't too harsh but for me this change is totally not working.
