I'm going to guess... neither. Both the people likely to read IGN or X-Play are hardcore gamers. So they by other sites info (and show?) know what they want.
You pretty much have to seek out either site. If I had a gun pointed to my head though and had to pick one i'd say IGN, because i don't know if X-play has more viewers then IGN or what... but i'd guess IGN influences people harder.
X-play is completly worthless to me though... both hosts are creepy and they're review score is out of 5... and they only use whole numbers... and their reviews have the depth of the kiddy pool in the Keebler elves treehouse factory.
