Much worse on the DS.
What's worse is, that this isn't 100% like the PC version. They've taken some stuff out or even moved it around.
The graphics are not that great, but fairly decent. You still get to see a lot of the movies/cut-scenes.
The sound however is horrendous! There's hardly any sound effects, and the music is louder blocking out what little sound effects there are. The only decent sound is in the cut scenes.
It's an okay game, but I paid $20 for it on the DS and only $10 on the PC. If you still want it that bad, wait until it goes down in price.
