Arc's extras were somewhat odd.
If you pre-ordered, you got the Arc boxed set [set was nice, nice hardbound instr book, a box with a plastic Arc memory card holder, some little cardboard plastic standee things, and 4 rubber analog stick covers with ARc characters on them], also you got a watch with one of 6 or so pictures on the face, in a nice metal case. It was not a wrist watch, but one of those that clip on to your belt loops. If you preordered from WD, you got those things and an Arc mousepad [again, multiple styles, no choice.]
WD wanted 74.99, I believe, for the game, watch, mousepad, and free FedEx shipping, which isn't actually that bad if you think that there were 3 [4 if you count Arc Arena] games in the set. But there was no game-only package, the extras [thumb covers, mem card case, standees] were packed in.
The punching puppet to me always seemed stupid. Different, yes, but stupid. I would have preferred a bobblehead or a stuffed animal or even a plastic action figure thing. [Last time I browsed ebay, one of the Arc watches was available for 1.00.]
I'm still on the fence about GG: deluxe. I don't 'need' a deck of cards, but it could be used; the soundtrack CD is always useful [assuming you like the music], and I doubt I'd actually wear the watch or necklace anywhere; but I've got enough credit at a store to get it with no cash out of pocket, and there's really not much else at that store that I'm interested in getting, so i might splurge to use up my credit and support WD's doing 'extra' for the fans. The extras for GG seem a little 'sturdier' than that for AtLC, if nothing else.
