The hype train has left the station. The more I look at GNR, the more I think it looks like another mb heavy JJP game with an amazing light show. For the money, I'm still going for avengers prem. Bottom line is they are going to appeal to different audiences and neither will have any effect on the value of other games.
If you want an insane light show with amazing theme integration and non-stop multiballs, GNR is your game.
If you value unique shots and flow, then Avengers is your game.
