I am a lifer on Champions Online as well. I can honestly say that you should not worry about this change. It has actually been a gigantic boon for the game. You will still get all your toys. The F2P'ers will have limitations about how they can play, unless they pay for it.
Where YOU benefit is the following: Content.
CO was effectively dead. No more than 1 zone per area. Nobody played it and there was no new content for more than a year.
Suddenly it went F2P and now massive amounts of content are being introduced. Every week something new is being added. The schedule for the calendar is also quite full for the next month or so.
It can only help the regular gaming community. This will help PvP, as lower level PvP tiers will be full again. Klingon players will have a lot more gamers over there, and the financial injection from hundreds of thousands of new people buying all the stuff on the C-store that we have already bought...
Well, that kind of financial injection will help feed more content into the game, when Cryptic is able to hire more people.
CO has had massive growth and success.. Now some zones have more than 18 instances of the same map, with 100 players per zone. .. where before.. 1 instance.. 10 players.
That is huge
We need it.
P.s. As a lifer in CO, I geto 400 Cryptic points a month, just for existing.. no doubt that will happen in STO.. That is 800 points I am going to get a month... and the game will eventually pay for itself.
