Well, that point applies to games you don't like, too, really since you'd theoretically have to describe the game and insert opinions on why you hate it, where it might be easier to focus on the positives.
But yeah, I get your point. Anyway, with my writing, I just... write, I guess. I try to make the game sound fun (or awful) depending on how I feel about it, as well as give the relevant essentials. I dunno. My process is kind of complicated. I guess if I could summarize it, I'd say that I just try to tell people what I think is important, and try to do that in an interesting and useful manner.
Really, you could argue that everyone has an opinion regardless of how they express it because, well, you wouldn't be reviewing if you didn't. Like... it's really hard not to be biased about a game, and that's why you write about it the way you do.
I get really, REALLY irritated when reviewers spend most of the review talking about graphics, storyline, and music, and just BARELY cover game play itself.
That's an interesting point. However, I honestly think that what's included in the game depends on the game. For example, if the game is heavily story-based, where the game play is pretty simple (like with an RPG), then there's less need to describe it. I think that point is more appropriate for the graphics/sound/music thing, though... Because to me, unless those things are particularly outstanding, I won't even mention them. And reading that thing in other reviews all the time (especially by the same reviewer) just feels like it's forced in there to account for everything there is.
Still, with the more major ones like story / game play, etc depending on the game, you can review it without mentioning one thing or another if one of these things is particularly strong and the thing that makes the game stand out.
Anyway, thanks for the comments (and discussion). Just out of curiosity, have you reviewed elsewhere before? You're new to this site, I can see, but you seem like you've come from somewhere else since you seem to know what you like and don't like with some conviction.
