I personally feel this site, which is supposed to be an enjoyable game, would become much, much, more of a mundane chore if I had to track all these things manually.
+ I like to play random map, I would be much much less inclined to play random map if I didn't have the side stats
+ If I ever get behind on my games and need to take my turns quickly because of real life situations, its nice to just glance over at side stats to get a quick overveiw and take my turn. This would be very difficult without stats.
+ Account sitters would be in the dark without side stats. I sit occasionally, and I find it hard to be super helpful. I couldn't imagine without stats
+ I like to spend more time conquering regions and clicking the assault button, rather than trying to estimate how many troops a player has.
+ Side stats make playing brand new maps easier to understand.
+ Noob players may not add up Troops Due on their own, and may be unhappy with their experience or accuse players of cheating.
+ Dont know why I used + signs
+ I am bored
