Low Price
A big factor in how fans evaluate games in this genre is the price, since Vampire Survivors is only 4.99 and many of the biggest games are free or have expansive free demos. This may not be entirely fair, apples to oranges in terms of what some of these games include, but if a game is 4.99 or less it gets a full point in low price by default. If there is a lot of value and the price is only a little higher it could still get a full point.
