Q: Can the game be loaded back into Unity?
A: Barely.
1) Most of the code linkages are dead. There are too many broken links.
2) The game is not well done. Many of the design-time editors are missing, unless you are willing to fork-out money to license all the vendor demos out (IMHO a bit of ridicule).
3) The game make no sense as to how it is done. They did everything wrong.
Q: If I want to make a cricket game what should I do?
A: Study hard, make other games in the mean time, apply for a job at their competitor* BigAnt or a reputable game studio. Invest in BigAnt and you can always go there for a shareholder meeting*
It depends what you want to do with your life. I don't think you love cricket to make a PC game for the next 5 years of your life. (Don't follow the same as how they did it, least you fall into their mistakes).
* Note: I am not part of nor affiliated with BigAnt. Just saying.

Further to that,
They used one of the best in-game weather systems, one of the best audio systems, one of the best particle & effects system, one of the best GUI systems, one of the best custom-modelling systems.
I don't know how they managed to create a game where the audio clips into the AI, the in-game weather looks terrible, the in-game stadiums looks terrible, the graphics looks bah, the UI looks outdated.
I don't know how the vendors would get affected. They probably would not get affected, and sweep it under the carpet.
The one most telling is the in-game weather system. That vendor is very reputable and very famous. To see such lousy weather in-game, it is let down.
