CFTBL is my #1 game all because of chasing that high score. Couldn't reach the 1 billion mark this year.
As for the rest, MM is next though my strategy doesn't change that much - just fun to play.
AFM.....just like hiting those ramps. Another great game.
Next is either one of the Popaduik games TOM or TOTAN - great to play but i wouldn't buy one to own.
Last game TAF which I own - brought purely for sentimental reasons and nostalgia. As for the gameplay.....let's just say that I am in no hurry to bring it home from the in laws place.
