Was watching a long play of Platoon on nes, and even though its a poorly made game the ending that sunsoft did for the nes version is amazing, I mean they literally animated the end of the movie, with film boarder and widescreen image, and by nes standards looks amazing. Here it is right here http://www.youtube.com/watch?v=Un9Wy-iKmp8&feature=youtu.be#t=14m51s Any other bad games that have surprisingly good endings?
Cyber-Lip has a pretty cool ending in the sense that it's not a happy ending...then again, if you actually played through a crappy, boring Contra clone only for it to be all for nothing you're probably going to be pretty annoyed.
