Which facts exactly ?
Game length ?
graphics fidelity ? What if it's stylised then ?
How to explain that the game is fun ? Could you understand its appeal from being tought the mechanics alone ?
How would you express the atmosphere of the game (if any) ?
Don't get me wrong, I don't really care about how they are today, and I think it would be more interesting to have a gameplay cut down rather than impressions, but then very few people would be able to do a good job at it, and you wouldn't read a review long after release...
(And you'd still have subjectivity inside...)
Fun and appeal are subjective qualities. The same that L.Schofield is actually implying that he will make up his own mind about.
And I agree with him. You don't need to explain to me how fun the game is to me, because that's not of any value. As your idea of fun may not correlate with mine because the aspects of a game, genre, mechanic etc that you value, I may not do so, and vice versa.
Reviews written around the idea of telling me "how fun" a game is aren't that useful to me. They may be for others, but not to me. I'd rather get the explicit facts about the game and it's design, whilst also not minding hearing a reviewer's qualitative analysis of the more intangible aspects, like the narrative quality and characterisation.
Somethiing like:
"Game A is an RPG with fairly complex but not confusing gameplay systems (similar to games such as X, Y, Z etc), stunning graphics but with a meandering story that doesn't really go anywhere. The performance on X platform suffers in certain sections of hgh activity (e.g. large battles and boss fights), however the imagine quality is impressive, sporting a full 1080p resolution and AA technique that seems to all but eleminate aliasing. The overall game design also impresses, with a massive persistent open world, filled with quest-giving NPCs and lots of intersting side-content to engage outside of the main quest. Environments are varied, as are the types of enemies and settings encourtered throughout the gameworld. The world also hides numerous secrets, unlocked through special quests which reward with unique loot items that add a real sense of accomplishment to their obtaining. Despite the overall story being a disappointment, the characters have some interesting dialogue and the settings, background lore and great atmosphere in each of the twelve individual world areas give more than enough to maintain a player's interest."
This combined with some video footage of the game would be easily enough for me to make my mind up about a game. This is essentially all i'm looking for.
