If you’ve played Rock Band 3, you’ve played the full version of Rock Band 4, and yes you’re reading that right.  RB4 is the first version of the plastic guitar game for the newest console generation, and I’m not saying it’s a stripped down version of RB3, but it’s a stripped down version of RB3.  With RB3 I had a wee bit over 700 songs to play from, with RB4 there’s about 200 tots.  They’re making noise about bringing over the other expansion packs to RB4, but there’s been no indication as to when that’s going to happen or not.

All that being said though, I’m really enjoying the game, it’s nice to get back into the rhythm games, they’ve been out of my life for way too long.
