Was going to post a new thread along similar to this one, but I'll add on here.
Caveat: Prior to this game, I had never played any RB/GH type game in my life.
Bought the LE set 5 weeks after it was released. Had to put it on layaway as I was spending my cash on the re-mastered CDs. Played the 1st time (on easy and was terrible!) and had a ball. For me, it brought back a sense of time and place, and I was a very happy camper.
Am still playing every chance I get, and don't see myself stopping anytime soon. Still not real good at it, but "It's Getting Better All The Time" (sorry!). The grandkids (10 & 8) are my band mates, and they love it also.
One plus for me is it got me digging out my older CDs, all the bands from that time period, both Brit & US, and listening to them again.
My biggest discovery since playing it is that playing RB2 is a disappointment. Bought it for $20. last weekend, thought the grandkids would like it, as a change. We played it a bit Sunday afternoon and evening, haven't played it since. We played the initial challenge hoping we could unlock some of the songs they wanted to play (1st peeve I have with the game). I was bass, granddaughter was on guitar and grandson was on drums, so singer was game provided. My granddaughter thought it was totally stupid to watch a skinny, shirtless bald guy with a green goatee see "We Got The Beat" by the Bangles. They also thought it was boring, just watching the band onstage all the time, as opposed to The Beatles and all the different backgrounds and venues. If having all the visual in TBRB was the reason the initial song list was only 45 songs, I'm glad they did it that way.
So I know I'm spoiled by TBRB, and I think they are too. RB2 is already collecting dust on the shelf.
