With Guild Wars 2 to be released soon I would think many other developers are watching it with interest . It appears that it will be the best selling mmo since Warcraft and have a long lasting impact on the mmo genre .If it does as well as expected then I imagine we will see a lot more buy to games flood the market in the coming years . This will inevitably mark the decline of subscription based games . For instance if you play something like WoW for a year it will cost you roughly 5 times what it costs you to play GW2 . Buy to play games will allow you to play multiple mmos without the worry of hitting the wall in freemium games , paying a monthly fee or having to spend money in a cash shop . Its clear they will be popular because of this . I don't think freemium/subs/cash shop based games will disapear overnight but I do think ten years time they will be few and far between . Even though Guild Wars1 was released a few years ago I think its this coming week that marks the true begining of the buy to play era .
