What makes you think RB is so much better than GH? I like both, I'm just curious of your opinion.
I loved GH when it first came out. But I got sick and tired of the lack of backwards compatability with the wireless controllers on the PS 3. Then when RB first came out, it kicked the crap out of GH, because being able to play with 4 people was so much more fun. The more I played it, the more I preferred it to GH. Once RB came out, I never played GH again. The track selection on RB was better, the character animations were better, the camera angles, the venues, RB was just an all-around better experience.
Then when GHWT came out, I gave it a shot because all the instruments were
SUPPOSEDLY going to be compatible with RB. Well the guitar worked, but the drums didn't. So I played GHWT with just the guitar for a few days, but it just wasn't as fun as RB. I thought the characters looked stupid compared to RB. Maybe I didn't play it long enough to get deep into the game, but it was never enough fun to make me want to. I returned GHWT after about a week.
