In that case I'd suggest that once the voting is closed, pick the 3 most voted titles and do an aftermatch where people could only vote for one of those three games.
That way, people would discuss (hopefully not in an agressive way) the merits of each title but also the problems of the others trying to convince the rest to vote the same games he/she has choosen.
Please excuse my bad English.
