Yes, it's a stupid question. Yes it probably has no consequences with regards to anything — sales, end quality, whatever — but there is a certain pleasure in debating who 'won' E3. Now that Sony and Microsoft had their conferences, and Nintendo did its thing with Nintendo Direct, maybe it's time to ask the big question: who 'won'?
I obviously have my own pointless opinions on who has performed best so far, but I'll leave it for you folks to discuss in the comments. AND VOTE!
