in rock band 2 you probably can do longer chains, because the trophies are displayed at the end of the song and there are like 20 or so trophies you can do within any given song, if you are playing with 4 players
edit:
for example all players play expert and do 100% (4) + the guitarist does a 100% solo with the secondary fret buttons on the RB guitar + gold stars + 1million points + 90 sec overdrive + 8x multiplyer for similtanous overdrive + winning a score duel/tug of war + winning against the last player that defeated you in a score duel/tug of war + deployed overdrive 4 times in a song + maybe it's even possible to make band savior (saving band members 3 times), while maintaining 100% for the other band members, if they die by overstrumming while still hitting all notes - that's 12-13 trophies you can chain
