Well I would prefer subscriptions if anything like that is required. A deal breaker would be the pay to win model. I don't mean micro-transaction specifically. I speak of the sort where you pretty much can't make it through the whole game without buying from the shop or where if someone comes in and two days into the game has a character better than what you've been working six months for. I prefer subscriptions if I have to put money in beyond initial purchase of the game. Everyone pays the same for an account, everyone is on equal footing with what is available to them. I also find that sub based games have better content updates because they don't have devs sitting around putting together yet another outfit for the cash shop. They get money by keeping people interested, new content does that rather well. Anyway, flaws with any system and all of that. Pay to win is my deal breaker.
