On one hand, Lightmare is bodying the living puffy out of Blizzard (47% vs 43%) which is awesome. On the other hand, it's a poll of roughly 2k people. Is MMObomb even well known? I know for sure i hadn't heard of it before this.
Anyway, not trying to take merit off of LM's current lead, especially because IW is the superior game indeed, but perhaps a poll should be made in a site where more people are aware of it.
