Getaway. Right now mine is on sebatical at a friends house due to a space issue. But it is still a great value game. Shallow rules, but buckets of fun.

BSD. As long as it is setup right, it is a spectacular game.

And as plenty have mentioned, Demo Man can be a blast. Great flow, and it has remained reasonably priced.

The only issue I have with doing it with math is that the Pinside top 100 is bullcrap. They are constantly manipulated by members of Pinside not rating the game, but rating their displeasure with other members ratings. That makes your main datapoint (ranking) invalid. That can't be diluted out as being across the board, because some games are more emotionally charged for people.

However, if you have games you love, cool, it works. But it only works when they are games you like. That's the most important thing in the equation.
