Falcon's Eye is a BBS door game from the 1990's. I used to play Solar Realms Elite by my friend Amit Patel. Falcon's Eye is a continuation of the game theme by Amit's brother, Mehul Patel.

Lately I've been interested in turn-based strategy games, so I've been researching old BBS door games that were popular back before first-person shooters.

Spell Casting

Base productivity is calculated
1. Number of current workers (push)
2. Base efficiency is 0.5
3. Increased by 0.2 for University (push)
4. Current number of workers subtracted by previous mult by effic (push)
5. Multiply number of workers by some real (0.0 in my case) == 0.0 (push)
6. Current workers multiplied by previous result (0.0) (pop)
7. Add previous worker efficiency (pop)
8. Previous workers by scaled new workers
9. If it's turn number one, make sure efficiency is 0.7
10. Truncate to [0.0, 1.0]
Mage-specific productivity is calculated
1. Racial modifiers added
2. School adds 0.03
3. Waterwheel adds 0.03
4. Cotton Mill adds 0.03
5. Circus subtracts 0.03
6. Falcon's Eye multiplies 1.1
7. Calc Approval Rating (20% sway to efficiency)
  1. Museum adds 2.0
  2. Town Hall adds 3.0
  3. Colliseum adds 2.0
  4. Total approval multiplied by 0.2
  5. Total approval divided by 100
  6. Add 0.9 to approval
8. Chance multiplied by adjusted approval rating
9. Check for something that mults by 1.25 if you don't have any (offset 0x262)
10. Truncate to [0.0,5.0]
Magic chances based on improvements
1. Mage population from last turn is multiplied by efficiency
2. Result is divided by number of free acres of land
3. Multiply by 1.2 for Oracle
4. Multiply by 1.5 for Tree of Life if Life Spell!
5. Multiply by 1.2 for Grove of Trees (if no target?)
6. Multiply by 1.5 for House of Spirits (if has target?)
7. Multiply by 1.25 for Concentrate Magic (if has target?)
Spell-specific chances
1. Spell difficulting is multiplied by normal magic chances (from last step)
2. Result is divided by 50
3. If protection is in effect multiply by 1.2
4. The result so far is A
5. Result is added to arg_4,6,8 (dunno yet)
6. Random:Real is called and multiplied by previous result called B
7. If A is greater or equal to B, succeeds.
