I don't think it's as horrific a list as I expected to be honest. Sure games like FIFA and FM are on there, but you're bound to get a load of people who only play these kinds of games voting for it.
At the end of the day this wasn't a list of informed gamers making a choice, it was the random public being asked 'so what games are you into?', and them saying 'I dunno, Halo?'
There are enough decent games on that list though. It's not bad.
