Anyways look at my plans below here and tell what you think.
Territory plans:
Each player on the field: 1B, 2B, 3B, SS, RF, CF, LF, P, C
Each base: 1st, 2nd, 3rd, Home
The Outfield: Left, Left-Center, Center, Right Center, Right
Bullpens: Home and Away
Dugouts: Home and Away
Batter: right and left side of the plate(although I may just have one batter)
Grandstands: 40-60 territories
Gameplay:
Grandstand areas of the same color will be able to attack adjacent territories of the same color.
A stairway/tunnel icon will indicate connection to others with the same icon. This will allow movement between colored grand stand areas.
I'm figuring the bonus structure for the Grandstands will just be the standard territory bonus, which works out nicely when you think about having more and more of the crowd get behind you, no "bonuses" for holding certain sections or color groups. Maybe even a increase/decreased adjustment based on the color of the stands you have. Like every 2 yellow territories gets you 1 army, since usually the most rabid fans are in the cheap seats, while the annoying cell phone talking fans are in the closer more expensive seats....(see: "HEY! look I'm on TV whenever a right handed batter is up!"

The outfield should connect to adjacent fields.
Bases one-way attack each other in order - 1st->2nd->3rd->Home
Infielders can attack adjacent bases
Batter(s) can bombard all fielders and field territories and 1 way attack to 1st Base.
The fielders will give bonuses for common double-plays (6-4-3, Around the Horn, Outfielder-cutoff man-catcher)
Connections between the dugout, bullpen and the pitcher.
Possible victory condition of holding all the bases and the batter(Grand Slam?)
Questions:
How to connect the field and the rest of the stadium?
Is this getting to complex already?
Give me your suggestions, please!
