Ok so been playing the game for a few hours (steam says 16) now through several diffrent versions here are some thoughts that I have had. not in any particular order and i guess some may already be in the pipeline.
I think newly unlocked buildings should flash or have at least some kind of indication on the gui that they are new.
the info panel you get when watching a player should on player disconnection say something like offline, cancelled sub etc rather than just switching to [no information]
tool tips on positive and negative buzz as to what the main factors are
I’ll add more later
