Science can now tell you whether or not a game is any good
I bet you love some terrible games. I do. Just Cause 2's plot-by-numbers and awful voice acting, for example, couldn't put me off it's intoxicating blend of grappling-hook action and big explosions. Dwarf Fortress looks like a spreadsheet circa 1987 and is about as comprehensible, but I can't help but get swept up in the lives of my little miners.
That's why I'm a little sceptical of the GameXplain , and Kotaku don't do scores. Ars Technica summed up the problems with review scores pretty well in this great article. Oh, and it's worth noting that games can get a positive review on Steam for $5.
So maybe it's best to stop looking at numbers and use your gut instead. If it's fun for you, it's fun for you, whatever an arbitrary number tells you.
