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 :(
Planetside is one I’ve always been interested in for the longest time, but I’ve always been on Xbox. Does it run on Steam Deck? I’d love to finally try it out.
There are reports of people getting it working that I heard. But I don’t think it is going to be a pleasant experience. Planetside 2 requires plenty of cpu horsepower.
