Quoted from John_I:As would a lot of them. Personally I will be happy with a tastefully done bootleg ROM done with Pinball Browser. The one in my Ironman VE is awesome with only a few changes. Just having Shoot to Thrill would have been enough to make me happy. The STLE one is great too. Not to mention you can pick your own songs if you know what you are doing.
When AC/DC was released, I would sing the praise of the jukebox concept over and over again. It was the greatest game I'd ever owned and you could pick a whole song out of a list of 12 classic AC/DC tracks for variety....then Metallica was released. My favourite band from high school.
Fast forward 4 years of ownership....go to play a game. Despite the variety in songs, it now seems like a chore listening to those tracks even though i still love the songs. In the case of Guardians of the Galaxy, I'm probably a bit younger than most hobbyists (?) and those songs have no connection to me whatsoever and the majority of the soundtrack music doesn't seem like they would fit into a game of fast pinball. Maybe snippets during multiball might be ok, but personally they'd get old fast if it was jukebox style. I like how Tron had some memorable soundtrack music, but also original pinball tracks in the same style. I think a happy medium with Guardians will be fine. Did 90s pinball machines suffer due to lack of movie soundtrack songs?
