yes... 8 out of 10 actually... some games (e.g. Nes DBZ 2, DBZ Gaiden etc..) like Nes DBZ 2 does have another story to beat... kinda like a secret boss fight.. it's Frieza Saga & after defeating Frieza... the credits rolls out.. then Vegeta turns Super Saiyan & Goku will need to beat him up, kinda like a 'What If' story.. now that's 1 of few rewarding titles i remembered~
