In 1988, you had some really cool RPG and adventure games on the PC too.
Bard's Tale III, Ultima V, King's Quest IV, Might & Magic II, Wizardry V, Police Quest 2 and the NES had Knight Rider, Willow (!) and Megaman 2!
It is also the year when Tetris emerged, why are none of these games on the list? 
Out of the ones you posted though, I'd give Contra and SMB 2 a shared first place.
