The winners of the yearly Oprainfall Gaming Awards are decided collectively by the gaming journalists and editors of the Operation Rainfall website.
Their rules regarding how the awards are handled:
All games that are exclusive or are multiplatforms that are universally better on one console are eligible for each console’s award.
If a game is on one company’s set of consoles, it can qualify for one or the other.
All multiplatform games must compete in the Mutliplatform category.
Winners of each category, as well as Download-Only, are eligible for Game of the Year.
