[quote name='bigdsinferno']order solus. that's the one i ordered and got game only. as for the wireless mics, i ordered them about 3 weeks ago and got a indefinite delay email... so, don't plan on getting these anytime soon.[/QUOTE]
i have singstar, gh, and rb. rock band's singing is definitely the easiest of the bunch, while gh and singstar are far more difficult. personally, i find singstar to be more accessible when it comes to parties. people tend to be intimidated by massive amounts of plastic instruments i have lying around. also, singstar is focused on vocals only, rock band is not, so if you are singing in rock band, you're more likely to spend a minute or two listening to music rather than singing. that really doesn't happen in singstar.
my personal preference is towards rock band merely because i like the variety and the fact that 4 people can play at a time (yes, i know singstar has pass the mic, but it's not fun). they're both great though and i wouldn't really pick one over the other as they both have great qualities. now, gh i can do without. rock band also has better dlc, the singstar dlc sucks, as it's euro-centric and i don't know more than 3/4 of what's on the singstore.
