How to get easy money (you'll need pole vault): 1) Go to Snowy Map 2) Get at least 2 groupies 3) Try to get in the skies and do a superman flip, but then after ride the reindeer 4) Defeat the boss 5) Do a couple of pole vaults and land them. There you should have about 30k+ money after the run.
There's a glitch/cheat. 1) Go the Target Game 2) Wait for the 10 seconds to end 3) Press M then press "no thanks" on submit score board. 4) Observe of how you see all the games randomly flash and say that you completed all of them. 5) Enjoy!
I hate for a fact that we can't choose between Running, Endurance and Reactions. It's somewhat annoying since you may feel uncomfortable to do all instead of just doing one. I hope you don't do this again and keep it how it was like it was before when we could pick!

There's been quite a high demand for ACTA - The Game, but I don't think there will be :P Sorry.
