I've had good taste in consoles over the years and haven't felt burned on any of them, but I have played with a few people look down on. I've had fun with everything I've played with so far. Even if the console bombed, as long as there is one worthwhile game I wouldn't call it crappy. I found an Odyssey 2 in my grandparent's basement. It's a very early console that I wouldn't recommend anyone go find, but I had a lot of fun with a game called K.C. Munchkin that was a Pac-Man like game with a few new ideas. My other grandparents had a Pong clone system of some type that I played as a kid when I was over there. It was fun enough, if you've played any version of pong you know what to expect. Finaly, the one type of system that I played a lot as a kid that most will say was awful, but that I'm going to defend, is the Tiger Electronics lcd games. These get way too much hate these days. I'm not going to say they hold up to a Gameboy, they don't, but there were good ones. I've got a bunch that still work, and some of them are fun even now. It came down to luck with these. They made so many of these things in such a short amount of time that most were awful. A few though, man they are works of art. Sonic 2 is the one that still impresses me. This is a game that has under water sections, loop de loops, multiple enemies, bosses that change every stage, and even a pinball stage. All on a system where no graphic can overlap with another. It's a masterclass in efficient graphics layout.
Oh, and when I went down stairs to check what the Odyssey 2 game that I liked was called, I found out I own an Atari 7200. I do not remember buying a 7200. I did, I'm looking at it, but I don't remember buying it or ever playing it.
