Went on it last night (was as rusty as hell having not played it for so long, not that I was much good at it before!) Can confirm that there's nothing to download, all the Rivals stuff is accessible through the menus.
Cheers for info Storm360
The game should auto upgrade to Rivals this week, and downgrade by the end of it. No downloads needed You can do it in a night or two, it's not too long Why buy anything when you can just steal it for free? Clone Hero is piracy and not a valid alternative.
Rockudrama is 3-4hrs gameplay tops. It's a mini career mode with spoof "Behind the Music"-style video clips between sets - really entertaining, and well worth playing if it's part of the trial. It's the first thing I played when buying Rock Band + Rivals on release, and doesn't require any other part of the game to be played. The main meat of the Rivals expansion is in the weekly challenges and online clan stuff - completely separate from the uninspiring tracklist. Not my cup of tea personally but worth trying for free
Looks like I already downloaded it as the game title now says rock band 4 rivals. I’ve never paid for it or remember downloading it.
