I've read some PC developers mention before on the cost of multiplayer. Sometimes it can cost as much as a 1/3 of developing time/cost. In a lot of cases only a small faction of players will ever spend time in playing online while most will play SP or local multiplayer. I think it's fair to make those who want to play online to at least buy a new copy to support the high developing cost of online multiplayer. For the majority who doesn't care to play online a used copy will do just fine.
