Just to add to the info and stuff....
Star trek Online went F2P some time ago. Since then the graphics have had a major overhaul, top notch for an MMO.
There have been several updates to the game. Events, missions, fleet owned starbases you can build etc etc.
Just because a game goes F2P does not mean it is dead. With the economy like it is F2P is probably going to be the future. Several games are already going the hybrid route. WoW, STO and now SWToR.
Give it some time. I bought lifetime sub for STO. I was furious when it went F2P thinking the game was dead. I was wrong. I took a few months off when it went F2P, came back to amazing graphics, almost ever bug was fixed, and more content then I could finish in months of casual play.
GW2 is going to be F2P. Personally I will never play it. Not fond of the game or the IP. So for now Im playing SWToR, WoW, STO, and The Secret World. I cant afford to play everything. And was fixing to cancel SWToR in favor of TSW. Now I can play all of them. Only paying monthly for WoW and TSW. I love this game, the PvP is the most fun ive had since DAoC. While not the same the warzones are unique and very fun. I pray for huttball to be brought to WoW actually
So in short, give it time. STO is far from dead and is steady being updated. Going F2P might give more a chance to play another game. We have to remember that games are for fun. As long as you have fun it doesn't matter what people say about it. If you log in and stop having fun then move on. If you have fun then enjoy the ride!
