I have no issues with the subscription models personally, in fact I'm currently paying one for an MMO. With that said I would like citations to the following arguments I've seen made in the last 2 pages. Citation other than "it's been proven, but I'm not going to be the one to prove it."
1. F2P/B2P ends up costing the consumer more than subscription.
2. F2P/B2P is an excuse to get free content.
3. F2P/B2P has a worse community than subscription MMO.
4. F2P/B2P business practices confuse the consumer & inhibit the game.
Most of these are directed at Ebonheart, as I've seen some really big claims with nothing to back them up. Using SWTOR is a great example that helps disprove many of these arguments. As restrictive as SWTOR's F2P model is, it's also one of the few MMO's that lets you purchase your way out of these restrictions with in-game currency. The laundry list of drawbacks can all be bought out. I would also argue that it's easier to do so in SWTOR than in other games that allow you to purchase store unlocks with in-game currency. I currently have a subscription to SWTOR because I enjoy the game enough and don't want to have to jump through those hoops, although I know how to do it. I know I'm paying more by a subscription, but it's such a small difference that it doesn't harm me financially and I feel I'm getting my money's worth.
I would like to further segway into another point. Many MMO's are now also using what's called the F2P Hybrid model. The keyword being hybrid. The hybrid is that you can continue to pay a subscription and bypass all of the F2P elements, or you can pick and choose your content. You have the option. This is probably the hardest thing for me to swallow when I see discussions like these. I 100% agree that some F2P models really shove it in your face, and it is really annoying trying to navigate through the system. But that argument is completely nullified when subscription is an option. Isn't it better the game support all walks of life? People of all financial levels? That's why I think the hybrid model is the best and I don't see the excuse not to offer both. It's all about choice. You can subscribe and all of the hoops listed disappear and cease to be an issue.
1. I have yet to see proof that F2P ends up costing the consumer more. This is from both personal experience and the lack of an actual citation proving otherwise.
2. F2P/B2P games are not only making a profit, but are making content updates regularly. So it's not just freeloaders by definition.
3. Unfounded. Subjective and nothing has been provided to quantify this as a fact.
4. Completely nullified by a hybrid model, but if the game doesn't support one then a legitimate argument can be made.
