My main answer is going to be the Intellivision and Colecovision. The controllers are awkward and cumbersome, and to my knowledge, there aren't any real stand-out titles that you can't find elsewhere.
Play AD&D on the Intellivision sometime. It's pretty great, and the Intellivision had some other stand out games too. I understand its appeal, but I also do not get the Colecovision.
I loved the Intellivision. It had some unique titles that you couldn't get on the 2600, which is the closest comparison. Sea Battle
, Space Hawk
, Triple Action
, stuff like that was great. (I really love the physics in Triple Action
's airplane game, you can stall your plane out and all sorts of stuff.)
The Colecovision was really a victim of bad timing. I think its appeal was a nearly arcade-perfect port of Donkey Kong
, and had the market not bombed like it did, perhaps it could have cashed in on some early NES-style support.
One I don't get is the Neo Geo Pocket and Neo Geo Pocket Color. I have never understood those systems' appeal.
If you love fighters, these systems are great. Some of the best portable experiences to be had at that time. SNK vs. Capcom: Match of the Millennium
is a legit great fighter. It also happened to have a few decent games outside that genre, like Faselei!
, Dark Arms
, a pretty solid Sonic
game, and some Metal Slug
