I think we all have a couple of games that are beyond saving (they are BAAAAD) but there are bits and pieces that are good so you desperately try to like them.
My game like this Lord of the Rings Book 1 (SNES). Probably one of the worst RPGs I've ever played (not quite as a bad as Hillsfar on the NES).
Unfortunately, it has some really, really great audio and while the graphics are bad the animation is fairly good; when you attack things it actually LOOKS like you are attacking (not just one animation frame of your character holding out a sword). So, the game feels like a terrific waste of terrific ambiance (I do love how much detail was put into things like grass that actually sways, ambient sound effects like dripping water and wind).
