The PS1 remake of Chrono Trigger. I played through it again just to see the new cutscenes. Turns out the only other thing they added to the game was several hours of lag. Every time you start a fight, it takes about 10 seconds to load, and then every time you end a fight, it takes another seconds to load. I would've been better off watching the scenes on YouTube and then playing the original on SNES again.
And I have a Mortal Kombat III game... for Game Boy. 2 buttons. Horribly broken. I'm still shocked that it actually got made.
