What is RB3 for you: mainly a game that uses music to provide fun ("game first") or music turned into a game that is meant to serve musical purposes ("music first")?
You can tell that by taking a look at some of your own preferences, for example:
- how much do you care about the charts being a correct representation of how the song is played by a real instrument VS how much is "fun" or challenging to get a high score
- how much interest do you have on Pro instruments
- how much do you care about animations, venues and general graphical appearance
- how much do you care about overdrives and other in-game concepts
I can for example tell I am firmly in the "music first" camp by the fact that I mostly play Pro Drums (with eDrums and MPA), Pro Keys, and sing. I neglect 5-lanes instruments (although I still have some fun with them) and play them only when someone else is already on the drums + the song has no Pro Keys + I am too tired to sing.
And also I can tell from the way I charted my few customs, wanting them to be full-band or nothing, being quite unforgiving to myself in the choice of notes, feeling frustrated every time a compromise is necessary (like dealing with the Pro Keys limited range), but then also wanting to get done with overdrives and venues a bit too quickly
So what's your own take on RB3, game first or music first?
