I tend to trust PCG UK reviews, they seem to be quite accurate in my experience. I may have not played a few games because they've rated them lowly and others love them though! For example they gave Hellgate: London 74%, about what I would give it basing my opinion on the demo - it's good (i thought), but I can imagine it becoming repetitive; it's certainly not bad though.
Then they give some games abysmal scores - think it was the Little Britain game, they gave 4% or so . Ratatouille around 40%.
One I found surprising was 85% for CoD4. Not giving into the hype to give a 90%+ score - which I agree with because the first game was totally awesome, but the scripted 'enemies from no-where' thing is getting a bit old now.
If they gave Crysis 99%, i'd believe they really thought that - because I think it's totally awesome .
As for Hexus reviews, I do hope you start putting %s; that's really what I look for after reading everything, as it's kind of a sum-up of "Should I or Shouldn't I?". I only really tend to get games that score 90% or over - unless i've been waiting ages for them, or just know i'll enjoy them (of course a 40% review would change my mind ). eg. Stalker got iirc 84% in PCG, but I was anticipating that for ages, and loved it . Another one: Evil Genius, 89% I think, was great fun - had to use money cheat though, was kinda solid otherwise (unless you just kept stealing money for hours before you interrogated the maid). Plus I always made my base rooms far more big and expensive than they had to be at the time - all in the grand scheme of things .
