It's between TNA and Houdini. Thay are 2 different style games. TNA easy to understand but challenging with superior light show and sound.
Houdini is a breath of fresh air. Art package is great, shots are good but very tight. The rules are very good. Not to easy and not to long. Best use of a LCD screen that I have seen. With Houdini you will have to learn how to make the tight shots or you will become very frustrated with it.
With both games the further you make the more rewarding it is (fun factor).
As for GOTG, no more and buy it and wait for it to be finished maybe. These are just my take on these games from an average player.
