I could go either way. For most games with micros F2P is probably the most profitable route. With FIFA, Madden, 2k, I'm just not as sure. There are a ton of people who play and don't spend on the pack modes. And the likely big spenders on sports games are probably already paying 70 for the privilege of spending all season long anyway. Are there enough potential whales out there, who don't already buy the games, to offset all those lost initial sales? Don't know either way if I'm being honest. Just find it less likely than I would for other genres.
