Nothing like the classics...
To me, the Famicom and Super Famicom were Nintendo's best game systems. This system is small and can fit into any entertainment center. There is also a disk system attachment for this system to play games on floppy disks (not the same size like computer disks). If you like to play the NES games, but also want to play the Japanese games, you need this system. Modifying the hardware on your NES will not make Famicom games work on an NES unless you have special adapters which are usually found in games like STACK-UP or GYROMITE. But it is just better to have the original.
Games I recommend are Zelda no Densetsu, Gradius II (not released on USA NES), Rockman 1-6, Super Mario 3, Super Mario 2 (not the USA version), Ganbare Goemon 2, Akumanjou Densetsu (better sound chip than USA Castlevania 3), Famicom Disk System, Splatterhouse Wanpaku Graffiti, Rockboard (just because it is an unreleased USA Megaman game), Samurai Pizza Cats, Star Wars (the platformer version that should be in a silver case), Final Fantasy 2 and 3, and Ike Ike Nekketsu Ice Hockey Bu (the characters from World Cup and River City Ransom).
The Famicom may be a simple machine, but it has MANY great games to make it worth the price. I found it annoying that it did not come with an AC adapter or AV cable. Just use any AV cable that works on a Super NES, Super Famicom, Gamecube, or Nintendo 64. The USA NES AC adapter should work on this system. The Super NES AC adapter doesn't fit on this system. If you have a Super Famicom AC Adapter, that will work too.
