The story is ok, I guess. You control a team of space scavengers who make their living spelunking gigantic, ancient spaceships floating in the cosmos. Sounds cute but your team can only have a max of 3 characters and this does feel very constricting when, later in the game, you face large groups of enemies. In general, get used to having your ass handed to you as a hat.
Why are these ships out there? Where is this base you start from where you pick up missions? How do you learn how to upgrade your equipment without randomly mashing icons and buttons until it seems you've made some sort of progress in ensuring your team is using up-to-level equipment?
DSD is one of those games that SHOULD be good. You WANT it to live up to it's, admittedly artistic, graphics. Unfortunately, it fails.
The combat is a card-based mini-game but despite my many upgrades and equipment swapping, I only see the same 5-8 cards. They vary per character depending on class, but it's not an exciting experience. At times, your character's "hand" is 5 Recharge Shield cards and no offensive options.
Making things worse is the lack of documentation. No one could slap together any sort of manual to answer any of these problems. There IS an in-game glossary but that's it.
They've released some DLC wherein you can now explore a bit of a planet for your missions along with the derelict ships, but, again, no documentation to tell you how it works and what to expect. You buy it, load the game, and see absolutely no indication that additional content has been added.
The cherry on top? I tweeted the "company" to inquire about some of these issues and their "rep" berated me for daring to ask his company about the product they offer. Good stuff. Really good stuff.
Don't waste your time. DSD looks good but there's nothing but confusion and frustration under the hood.
Fuck you, DSD.
