I think they are two different games for two different players. TH is great to look at, lots of attention to detail. That being said it is a wide body which will never be as fast.
GB may not be as beautiful to look at but is a fun fast playing game that keeps you coming back for more and more.
Decide what player you are and pick the one that suites you best.
Replying back to the person who questioned if JJP was in trouble if the TH flops. I dont think so. If I was the investors and saw TH flop, I would think to myself that was before I stepped in and too many things were already in motion that I had no control of. If I was an investor, I would stick through to oversee full production of the next game. Let that be the litmus test to see how JJP will do. If they can have a hit similar to WOZ, it should be smooth sailing, but if the third game is a fail and or similar issues happen like they did with TH, then they may really be in trouble.
