Due to a lack of votes, there are quite a few "joint" titles. And it's a top 12 not a top 25, due to too much statistical noise below that point.
48 votes total, 131 different games voted for

If you voted for any of these, a few short words about why would be appreciated.
Some interesting votes included Dizzy, Snake II and 5 different Need for Speed games. If you want to write a short work on any game you voted for which DIDN'T make it, but you felt it deserved to, say why here!
