EEDAR: High review scores influence “positive word-of-mouth recommendations”

Wednesday, 7th July 2010 12:08 GMT By Patrick Garratt


EEDAR’s said that review scores do make a difference to game sales, heavily impacting whether or not players will recommend titles to others.

The research body, basing findings on a survey, has claimed that, “The relationship between video game sales and professional review scores are not correlative but causal.”

More specifically, EEDAR said the study “suggests that high critic reviews have a strong positive impact on the likelihood of positive word-of-mouth recommendations. Professional critic reviews act as a multiplier for the likelihood of a consumer positively recommending the game to a friend.”

The debate as to whether review scores really do impact game sales is an unending one, but EEDAR appears to have drawn a line under the matter.

“As painful as it may be for developers to consider, even with the creation of a high quality game, a game is likely to achieve greater commercial success if reviewed highly, than if reviewed poorly or not at all,” the research body said.

The workings of the study were based on getting three groups of people to play Plants Vs Zombies. One group was told the game had scored well, another was told the game had scored badly and another was used as a control, not being exposed to any review information.

“The group shown high review scores prior to playing Plants vs. Zombies gave the game a mean review score 20% higher (14 points) than the group shown low review scores,” said the firm.

“This group also gave the game a mean review score 8 percent (6 points) higher than the control group with no review score anchor.”

Furthermore, “91% of participants shown high review scores for Plants vs. Zombies would recommend the product to a friend, compared to only 65% of participants shown low review scores and 79% of participants shown no review.”

Thanks, IndustryGamers.

    We live in an era of extreme information. Everyone has an opinion to share and it’s up to the customer to filter out the really meaningful stuff.

    When you are a real fan, a bit hardcore gamer, you search the web for relevant info. When you are casual, you walk into a store or visit an online retailer, look at some pics and the description and you decide whether to buy it or not.

    Reviews are nice entertainment but they are still the opinion of just 1 person. Find your editorial soulmate online and you have an opinion that matters to you.

    @1: if you looked at multiple reviews, you should be warned. Metacritic score of 46, with reviews ranging 2 to 7.

    This is almost something Pachter would say. It’s certainly obvious enough.

    …and negative reviews highly influences negative word-of-mouth. I wonder how many who currently hate on Alpha Protocol actually played it, for instance?

    It mostly affects lesser known games. For example, I know nothing about a title like Sniper: Ghost Warrior and wasn’t sure if I want it or not but after seeing Eurogamer’s 2/10, I’ve decided to forget about it and tell people that had asked me about it to do the same.
    Then there is a game like Crackdown 2 which isn’t getting horrible reviews but for an exclusive, isn’t doing too good either but since I LOVED original Crackdown, I’m getting this one regardless of review scores.

    This type of thing never influences me anymore.

    I enjoy a load of games that others simply hate. And I can’t stand playing stuff that often gets glowing reviews.

    It isn’t a matter of liking bad games or hating good ones. but just a matter of understanding that what appeals to me differes from others. As you age, you will find this to be true.

    What some teen or young 20something enjoys doesn’t tip my interest at all. Different demographics is all. I don’t enjoy teen scream flicks anymore either. Same type of thing.

    I got Sniper:GW too. I’ve yet to have a proper crack at it though.
