Graphics: It's a Playstation port/remake of two classic NES titles. Not impressive, roughly GBA level, but still an improvement from the original.
Controls: They worked well.
Music: Very good. Basically the same as the originals.
Story: You control four holy warriors that were prophesied to... blah blah blah. These are the games that started most RPG cliches. The opening lines are so generic that it almost sounds like a parody. Given its age, no one can really be blamed for this. Nevertheless, this may be an issue for newer gamers.
Basically, If you're a fan of old-school RPGs, you'll be in heaven. If you are somewhat interested in retro gaming, you may like this. In either event, I wouldn't suggest paying more than $10-$15 for it.
