Small update for those interested:
Simulation engine is almost done with a few exceptions. (Note: It was already pretty close but needed a few tweaks.)
1. I still need to implement strategies, currently the game chooses based on down and distance as well as field position.
2. I need to implement saving results and stats to the database.
Once I complete those (this is a slow process for me as previously mentioned due to time constraints) I might be ready for an alpha version for consumers to try it out. Much of the game is not completed but if results can be generated and saved at least I'll be ready to let people do testing.
