Ive played both.... GHWT has cartoony graphics, and looks horrible. The character custimization also sucks as well. It is exactly like Rock band 1 but with crappy graphics. The songs as well are way to easy, and way easier than most of the songs on rock band 2. You want good songs? Hard songs?Btr Graphics? Well choose rock band 2. Ive played both btw... I shit my pants laughing when i saw how huge the guitars were in GHWT. It looked rlly lame... Btw in rock band 2 you got challenges, online world tour... Practice mode, and freestyle mode. Not to mention you can go breakneck speed XD
GHWT sooooo much better character custimation rocks my person almost is a double of me makeing your own guitar etc is prety cool but i wish you could buy real guitars graphics are better than the others but still rubbish lol . More songs than RB2 and you can make your own. better drums and guitar thn RB2. One thing tht RB2 is better for is tht they dont add notes that arnt there.
GHWT is way better because of the live experience, the new guitars and the drumset, and the fact that you can make and publish your own songs, thats wicked and way better than rockband 2.
