By all means recommend or do not recommend a game, just refrain from using language that tells readers how to decide like, "you should play or buy this" or "save your money/do not buy". It comes off as superiority. And word the recommendation within the review. If you apply a score people tend to not even read your work. They'll just see a high score without knowing why it's high and potentially end up hating the game because it isn't for them. Don't be like everyone else that feeds into peoples laziness just to have metecritic recognize you as a reputable source. Add a comments section for user reviews or for Q & A. Keep it simple.
No score or rating should be given. Simply write about an accurate depiction of a game and an opinion playing it. Do NOT tell people to either buy it or pass. Leave that up to the reader to decide. Refrain from telling others how to think and that your opinion is the correct one for everyone.
