Quoted from HighProtein:Transformers for me is a certainty.
Attack from Mars is pretty much a certainty as well.
Based on the goals (broad appeal, earnings, fun with beers, etc.), well, TF would definitely NOT be a 'certainty,' much less a viable option. Limited (but avid) fan base, and the premium cost of a new release subtracts from those earnings. Best bet is to go for classic, "bang for the buck" games with broad appeal. This also rules out some great games like MB, AFM, etc.
I do see lots of good choices here. Tought to list just 10, but here goes:
Fishtales
Addams Family
A DE game (Last Action Hero or WWF or Tales from the Crypt or Rocky&Bullwinkle)
Spiderman (best bar game of the recent Sterns imo)
Big Buck Hunter (bar appeal)
A classic Stern like Big Game
An EM game, 2-4 player, with spinners and/or drop targets (Mars Trek, a poker-themed game, etc.)
Countdown (agree with Guy--love this old SS game!)
World Poker Tour (very addictive and fun when set up well; open pf is not intimidating)
A fast bang-for-the-buck game like Johnny Mnemonic, Jurassic Park, Maverick, etc.
This is pretty random, but I do agree with some others here that a mix of game types is preferable, esp. with a 10-game lineup. Something beyond the recent Sterns and 90's BLY/WMS stuff.
