EBA1- I could never really get into playing guitar hero. I never knew many of the songs, nor cared, each stage is wild yes, but zombie crowds jumping, and random weird people on set singing off cue with music made it a unmemorable experience. If you go to buy G.H, it is because you enjoy the songs, and care less about story, humor, and in some cases gameplay (for me at least).
Elite Beat Agents are VERY creative. I heard the rave about EBA, but viewing it as a G.H clone, I never cared to play it, I recently rented it, and I LOVE IT. True, it has fewer songs, and less qualities then G.H, but it makes up with it other qualities. I LOVE the humor, gameplay, and humor. Dancing to get a date, stop the rain, killing zombies, and destroying aliens is priceless. At first I didn't know many songs, but I knew a few like Y.M.C.A. and some others. I found I grew to love the others as well. The agents them selves are great and funny, and I LOVE THE ARTWORK!
EBA2- (I gotta go soon, so I can't type too much)
1. They NEED to keep same artest, they need that same art style that they have.
2. Try to fit more music on.
3. Bring back some old characters for kicks, and add some rememberable new ones.
4. More endings?
5. M.J's Thriller
