Heres my pennys worth.
When WoW came out I paid £30 for it, I played i and played it and couldnt stop playing it, I wanted to play and get everything done I could. it was £8.99 a month as well.
When Conan came out I paid £30 for it, I played it and then turned m PC off and watched some TV. it cost £9.99 a month as well. I dont find myself wanting to play it all the time.
Why the differences ? Well before any of these I played UO, i got ganked, my stuff stolen, and got pretty mad, but I still played it alllll the time so i ruled out the PvP.
AoC just feels not as complete as WoW was when it came out, im not going to compare then as they re now because WoW wins hand down, but it has had 3+ years to mature. I like the party system in WoW more, and where are the instances in AoC before level 35+ ??? It feels like a single player game. And yes I am in the OcUK guild on Dagon, so im not playing it single on purpose.
I will give it 60 days and see what happens, my advice to anyone would be play he WoW free trial, and play the AoC one if you can get it. See what you like but atm personally I won't be paying £10 a month to play AoC until they fix it and add more content.
Long story short WoWs £8.99 is a lot better value for money than AoCs £9.99
EDIT : The other thing that REALLY irks me, the AoC official forums can ONLY be seen by subscribers. Now atm im a subscriber so I can read it, but if you could see it as an outsider I dont think it would make you want to play the game. Something to hide because of all the criticism.
