This week's OnLive $5 Friday deal is Mafia II.
I really loved this game when it came out last fall. A nice, good open world romp, with a different, more story driven structure than most open world games.
Nothing too revolutionary here, just solid game play all around, a great story, one of the most memorable endings ever in a game, and impossible to pass up for $5 if you do not already own it (or have not already played it).
Once again, this promo price ends tonight at midnight Pacific, so if you are even half way interested, hop over to OnLive, play the first half hour of the game for free on OnLive's servers, and take it from there.
