The answer to the title of your post is yes and no. This can be a challenging machine and you haven't owned it for very long. Be patient and work your way up.
This game does a very nice job of tying everything together. This goes for point accumulation as well.
Don't try to conquer this machine all at once. Get good at one thing at a time.
Suggestions:
1) Work the ramps, get your shots down. This scores immediately obviously but the bigger payoffs come later as 2 of the Gothic events involve ramps, then you have the multi-ball jackpots and eventually the ramp bonus. Getting the ramps down first will also do wonders for the flow of the game.
2) Try your best to practice the same Gotham Event repetitively. The game allows you to lock into a particular event until you start it. Also my machine has a tendency to start the game on one or two in particular and then you can launch and start it. As you get better at the various events your points will sky-rocket from 10m... up...up... up to almost 200million for a successful event!

3) Get better at the right orbit. This leads to more event opportunities via the kick-out and/or increased chances to light the B-A-T rollovers which multiply the bonus.

4) I like to lock at least one out of the first two balls. Easier multi-ball.

5) If you are having a good game or when all else fails you might gamble on Mr. E. Some rewards are not that great but the list does include extra ball and extra ball is lit as well as that awesome 20x bonus!

Well those are some of my tips.
Now start to bring all these together during your game play and your scores are sure to increase. We have had this game for several months now and I have improved considerably. Hit 3billion once and can nail 2billion semi-regularly. Great game, glad you like it, and many happy high scores!

Spelling out C-A-V-E is indeed difficult. However, the pay-off is terrific if you succeed AND you light a hurry-up extra ball! Be glad the game is challenging instead of "can't wait to get rid of it" easy.
