superhero board game

I'm working on a super hero board game and it's becoming quite complex. I'm wondering if I should continue or not at this stage.

Here is some information.
[ ] Object of Heroes Wanted

Attention heroes. Ultra City wants you.

The once thriving city of Ultra has hit on hard times. Criminal control the streets, businesses are failing, people are dying. Thanks to a new government stimulus package, we are able to offer large cash rewards for bringing these criminals to justice.

So, if you are hero, come to Ultra City… We need you.

[ ] Ultra Heroes is split into three phases.

Crime prevention phase
Player draws an event card. Most events involve drawing one of more from the villains deck, and one of more locations. The other players rush to defeat the villains which are played by the player who drew the cards. If any of the villains succeed in there attempt and manage to escape, the players own hero will receive favor.

Business development phase
Some of the biggest heroes have the biggest corporations behind them. It doesn’t hurt having a few million in disposable cash. During this phase, you can purchase properties, take on contracts and invest money earned. Your never going to get that secret lair working just a day job.

Public relations phase
A famous hero who is business wise is a wealthy hero. Well liked heroes are more likely to get called first by the city mayor while other heroes have to listen in on police scanners.

[ ] Winning the game

The object of Heroes Wanted is to clean up the city streets. This can be done multiple ways.

Driving out the bad guys method
Each hero has a Fear / Fame Factor (FFF) and each villain has a Fear Tolerance Level (FTL). If a heroes FFF rises high enough, villains with low FTL begin to leave the city. Drive out enough villains to win the game.

Rejuvenate the city method
Criminals of Ultra city have spent considerable effort making the streets dark, dangerous and daunting as they are. By buying up businesses, you restore the cities economy and hope.

Capturing the King Pins
Ultra city is run by three mobsters who direct all the criminal activity. Once all three have been captured, the game ends. Don’t expect it too be easy as these guys are the biggest; meanest crooks your ever meet.

That's the basic idea.
I have a combat system worked out, a detailed map process up and running.
Stats and effects are done.
I haven't done any powers, weapons, vehicles yet.
In theory, I'm about 20% done.
Do you think I should continue?

This game is not based on marvel, DC or any other universe. Players make there own heroes from a choice of 50 powers and abilities.

thanks
