Research (Mechanic)

Researching is an important mechanic in Astroneer, as the player is required to unlock new schematic in order to make progress. Repeated researches performed upon researched Research Item will result in a resource instead of new schematics. To compensate this, if the player has no new schematic to unlock, then the research item will not be expended so the player may continue their research progress after an update.

Reward Category & Weighted Randomization
The new reward system, to say it in more simple terms:
 * 1) Schematics are unlocked by research item within a different category
 * 2) Specific type of research item includes: artificial, rock, organic, etc
 * 3) Different type of tech = different type of research item
 * 4) When you've unlocked a new tech (within a category), chances of unlocking a new one (within a category) reduced
 * 5) That mean, you may receive resource in place of new tech even if you've haven't researched that specific item
 * 6) * The more tech you've researched, the harder it is for you to research a newer tech
