I have never played seawitch but heard good things and even though this has no ramps it could be fun. On a recent trip to the Gold Coast I played Big Juicy Melons (WNBJM) and Total Nuclear Annihilation (TNA) both cool, especially TNA, which was fast, sounded great and was a challenge.
I just worry about the price of this game, rumour is the base model is $7500 USD so probably be similar to Batman 66 pricing, so possibly $12.5k for a Gold up to $25k for a Diamond - that is a heap of cash and wouldn't be surprised if the Diamond version is alot more.
Apparently the Beatles license cost $1 million and limited to 1964 games
