Shift/YMMV


 * Even Better Sequel: The second game is widely regarded as this.
 * Porting Disaster: Shift Freedom, a port of AltShift for the iPhone, is plagued with crippling lag and more than a few Game Breaking Bugs.
 * Sequelitis: Lampshaded in Shift 4's ending, but some people do think the third and fourth installments weren't as good as the second.
