Interesting post.
GHWT is nice and all but I'm enamoured with Rock Band style and uniqueness, not to mention the lack of DLC for GHWT.
I've dowloaded 5 GB of songs from the RB's Store so I'm going to buy GHWT alone and most probably not the 1st day because Rock Band drew me in immediately and takes up like 95% of my gaming time.
As you already pointed out, Rock Band's presentation is unique. It's all in the small details.....
- The whole band introduction before songs (specially if you created a character with similar features as yourself -or your soulmate, a relative, friend, etc- in real life with the same hair colour, eye colour, hair style, body shape as you).
- The "simple" but truly strategic use of the Overdrive.... Yes, I find that somewhat strategic and I was a avid RTS gamer -mainly Age of Empires- back in the day
- Watching the guitarrist or bassist playing the same notes a real life guitarist or bassist would
- Or the crowd singing along and when you miss a note that kills the buzz they change from singing along to a more generic cheering
- Or seeing the guitarist singing along with the singer while looking at each other in an accomplice way (with a perfect labial synchronization btw)....
- When the screen flashes like the old black and white films, or when the image "splits" in two mirror images (an effect which looks astonishing), etc etc etc etc.
These are the *tiny little* details that separate the good games from the great and incredibly prodigious games like Rock Band.
Other than that, both franchises are infinitely fun.
Also, Red Octane's peripherals are highly reliable. Heck, my old Xplorer guitar from Guitar Hero 2 still works perfect to date.
The mic is free as I use the 360's headset and it works quite well.... I have RB's drums so I'm not that much interested in GHWT drum set, but the addition of one extra cymbal is a welcome one and being able to use the Overdrive whenever you want is good too. In RB I tend to wait for the drummer to activate the Overdrive if I'm a guitarist or bassist.
The 6th note feature is a good addition too, but I'd miss the RB's Bass Groove.
All in all, both games are great but my mind exposes a very strong weakness for Rock Band.
