To your point about writing songs: Yeah well, not many of us can sing either, that may be why they never put it in. Plus the game can't recognize words, so it'd be impossible for it to make a lyrics list so the person can read and sing your custom song. With that in mind I think it's actually a better choice not to have custom vocals.
And if anyone was actually keeping up with Guitar Hero (which most of you don't, I don't see why you're all such no-it-alls) you'd know that they have MAJOR plans for DLC. Their adding it to the WII also.
They have said they are going to have a lot of DLC since they released GH2 for the 360 and have failed. I will give them the benefit of the doubt. However, comparing so far, RB has been better than GH. They have a lot of ground to make up to catch up to the amount of songs RB has. Nobody has even mentioned, besides me, the fact that RB1 songs (all but 3 which makes 55) can be copied over to be played in RB2 for about $5. GH has nothing like that and have not announced they plan to do that from previous versions of GH. That is a MAJOR thing RB has over GH. Just add the 55 songs from RB1 to the 84 on the RB2 disc and already, RB players have 139 songs without even having a single DLC song on it!! I respect people's opinion that they think GH is better to them, but please respect people who think RB is better than GH. I like them both. I like songs from each. I just made a point to say so far, GH has not had even 1/10th the amount of DLC that RB has had and that is because Harmonix has supported the game for expandability, where GH has not. I am not going to express here why the GH makers have not had that much DLC and yes, I do have my opinion on it. I will say it again, those people who like GH better, great. Those who like RB better, great. However, don't say a game is millions better just because you like it better. Give examples like I did to support your opinion. We will see if GH has DLC support better than it has and hopefully it will be cheaper like it is for RB.
