I know...i was really struggling with the decision of which to buy...the year or lifetime...I was this close to getting the lifetime but I reconsidered. I doubt I'll be playing this game for a solid year, let alone 2 years or even more...so I went with the yearly sub. I'll try to keep up with this game for as long as I can...and if I'm still playing after the first year, then I suppose I'll just buy a second year.
And if I'm still playing after 2 years (the equivalent price of a life sub at that point), then well...I'll just be risking that.
Besides, a year from now I'll probably be playing Star Wars KOTR
