Recently they brought back the life-time subscription option, and for US$199 you can play LoTRO for as long as you want, anytime you want.
I really enjoyed playing my hunter back in the day, before the expansions, and I've been told the expansions are decent. So I signed up for the life sub. I think it's worth it, and in less than 2 years of playing, I'll have paid it off - rather than an expensive monthly sub.
Just thought I'd see if anyone is around on the game. If not, you should consider the sub option... it's awesome.
