On steam, it gives two options. LIF:YO Or a 2-pack... What is a two pack!? What should I buy in order to play? the two pack costs extra, why? PLEASE HELP
Also, do you just have to make one payment or is it a monthly thing???
2-pack = Two Steam keys. So for instance, for you and your friend. You save about 19% when buying 2-pack, so if you have somebody close, who would like to play with you, family, friend etc, you can invest in that and play together. It's B2P, so you only need to pay once and you're good to go. In addition to that, owners of LiF:YO will receive one free character access in the upcoming MMO version of the game. You can read about differences between them here.
