Feel same as most comments. Tough call. I almost pulled trigger on a MET pro earlier this year. Not a big fan of music but liking gameplay more and more as I play it. There are a lot of rules but I like how easy it is to pick up on the basics. GB does have that new game high. I only played a few games but really enjoyed it. Looks awesome, interesting layout, fun theme, great toys, and code pretty decent. Downside is that some of the shots are extremely tight and overall a rough game. Need to play it more to get a better feel for modes. Being on the tough side isn't all bad but could get frustrating. If you have the budget and room, get MET now and GB next year. MET will be out of production soon and GB will no doubt be for sale a long while. You also get the benefit of the kinks getting worked out and better code at purchase. If you can only get one, I say GB.
