Sega Master System
More powerful hardware than the NES but that doesn't matter when the games aren't there. At least it got better support outside of the US such as the UK.
This is a bit of an understatement.
I always felt the Master System had better graphic capabilities than the NES.
Outside of the US/Japan, the Master System completely crushed the NES. There are a lot of reasons why this happened (e.g. market penetration, licensing agreements, etc...). New games were produced on the Master System well into the mid-to-late 90's in areas like Brazil - many of them ports of Genesis and Game Gear games.
