Thus, a point you seem to be forgetting is what is Turbine doing to make the P2P players happy? If they don't keep the P2P players happy, suddenly DDO will see a HUGE drop in profit. The highest priced quest pack I think is Giant Hold at 995 TP's so about $11 to buy it. How long do you think it took to make that pack? It's a huge map, with 10 dungeons and a raid and very nice loot that even lv 20's still run w/o being epic. But then, a F2P player can buy it for under the cost of 1 month of a P2P player. There's no way that Turbine (or anyone else really) could produce such high quality content faster. So, there has to be SOMETHING to keep the P2P players content to continue to pay a monthly fee. The only way Turbine could equal the costs out for P2P vs F2P players is to start charging packs at 4-5x their current TP's.
Are they nickle and diming F2P players? Yup, they are. But at a cost of less then a fast food meal, it's not that hard to swallow. And it might even be good for my waist line. You also seem to be thinking that it should be free? There's no level sigils in WoW... but last I checked, you couldn't go above lv 60 unless you buy 1 expansion, lv 70 w/o another expansion and soon not to lv 85 w/o purchasing another expansion... of which if you want lv 85, you need to own all 3. You're not going to be in many raids at lv 60 when all the good stuff is at 85.
Ultimately, I want Turbine to keep DDO up for many more months to come. But it needs to be profitable to remain open. No company in their right mind would continue to operate a business that's barely making it into the black each month. One big disaster can ruin them. There's also many factors that neither you or I can judge. What is Turbine's profit margin in DDO? What will become of the lawsuit between them and Atari? Is it possible for a 3rd company to undermine and/or buy out the rights to DDO?
How close was DDO to the red before F2P was introduced? No one but inside personal have that info and it would never be released to the public until quarterly earnings are posted and even then, DDO would be mixed in with their other MMO's. We could all log in tomorrow and be locked out of game. Someone might have just bought 10,000 TP's and the world servers are brought down. You could visit the DDO forum page to be welcomed with a huge "We're Closed" sign. The question for all players, P2P and F2P is, "did you have fun playing the game while we had it"? I for one can honestly say yes I did. That includes having to buy sigils when I couldn't find them.
