Personally, if I was doing professional reviews, the structure would be:
-No scores - instead, my bookending equivalent to scores would be a section I would call "Quote Me On That" - essentially a simple line or two that sums up my thoughts on the game. Something that's easy to remember and say in casual conversation.
-Have a separate section for the objective (technical stuff like frame rate and just describing the mechanics of the game) and the subjective (my actual opinions on the objective aspects, such as how I feel it controls, as well as stuff that's completely subjective, like my interest in the soundtrack or something).
-Clearly state whether or not I'm an established fan of the genre/franchise, and how this may have effected things (e.g if it's a complex game in an established franchise I've never tried, I'd probably say something like "newcomers like myself might struggle to get into it at first, but veterans should feel right at home").
-If it's a case where I really need a second opinion on something, I would have a little section for that. Like, an established fan of the franchise the game I am reviewing is from, because maybe I feel like I need that if it's a complex series I am new to.
That might be too different to the norm though to be accepted in the current climate of the industry.
