Sprite Archive Rating System
There are two ratings, each ranging from 1-5 (5 being superior). The first number indicates breadth, and the second indicates depth. For example, a rating of 5-2 would describe a site that covers many games but doesn't have too many sprites for each game, while a rating of 1-5 would describe a specialty site that covers a few games comprehensively.
Breadth: How many games are covered?
5: 100 or more games
4: 30-99 games
3: 20-30 games
2: 10-19 games
1: Fewer than 10 games
Depth: How thoroughly is each game covered?
5: Exhaustive, with little or nothing missing.
4: Thorough, but with some gaps in content.
3: Adequate, but with noticeable gaps in content.
2: Mediocre, with huge gaps in content.
1: Poor, with only a few sprites for each game.
