What's your favorite game you never hear anybody talk about?
Mine has to be Dragon Quest: Rocket Slime, a DS spin off of the Dragon Quest series that sees you playing as a slime operating a tank and rescuing the people from your town. You run around the overworld, collecting items to use as ammunition and saving money to upgrade your tank. The art and music are just as great as you'd expect from the Dragon Quest series. It made fantastic use of the DS's dual screens. It's also written for a younger audience, so a lot of it is just really silly and fun! Try it out for sure, I'm so sad there's no sequel :(
Solar Jetman for the NES. A really unique game that was well ahead of it's time, featuring exploration, problem solving, cut-scenes, great music, and multiple planets to explore with different gravities. Your mission is to repair your spacecraft by finding missing parts, and you can use a small craft or leave the vehicle and boost around with a jetpack with your spacesuit.
Yes, Solar Jetman was terrific! An underrated highlight of the Pickford Bros' output. It's like Gravitar but much less frustrating.
It's not well known, but Rare commissioned ports of it for home computers that were never released. The Commodore 64 version was found and can be downloaded from this page.
