Unlock Vince McMahon easily:
----------------------------
Choose to play as a GM in 24/7 mode. Choose a pre-set roster, and set your 
champions. Go forward a couple of weeks into the calendar, and simulate matches 
up until that date. Renew the contracts of a few of your superstars for as long 
as is possible (make sure you include your champions). Go to the calendar, 
select a date just before the contracts expire, and choose to simulate up until 
this point. You will have made enough to renew the contracts again. Repeat the 
same procedure until you get to WrestleMania. You should get there with a couple 
of decent superstars to compete in a championship match. Put the championship on 
the line, and fight the match to unlock Vince McMahon.

Easy money:
-----------
Start a game in 24/7 mode with a superstar that is 90 or better overall in 
attributes. Go to the calendar, scroll down to WrestleMania, and select it. 
Choose to simulate all matches up to this date. You should get a lot of money. 
Save the game, and repeat this as many times as desired to get an unlimited 
amount of money.
