And why not?
This is not a F2P game, this is a P2P game it just does not have monthly subscription system.
Said that, let's take into consideration monthly subscription systems.
You are paying an average of 14-15 USD per month for a sub on P2P games on the market.
So a LIFE, that allows you to play several months is in my opinion worth let's say.. 3 month's sub fee.
Of course there will be some extremists that will die several times a day and spend their lifespan in one month. But I do believe that for majority of players paying the above mentioned amount for a life is pure win.
And for the game / expansion prices?
I am ok with paying between $35 and $50 for the game as those are the regular game prices on the market.
Expansions tend to be just a little bit cheaper so anything between $30 and $45 is reasonable in my opinion.
Bear that in mind, that CoE with all its involving mechanics will probably encourage a focus on 1 max 2 characters per account, for a player to be able to experience the best immersion in game, and to live the life of your character to its best.
I do believe that if you intend to play CoE like other MMO's where it is common to create and then play 5+ characters in one month time, you should think about all of the character’s life that will pass by if you focus your available game time on playing other characters.
And should you play one character most of the time, just put those $10+ bucks every month in the piggy bank and you will have more than enough to satisfy the cost of purchasing a new LIFE in few months when your character is finally free of the burdens of this physical world.
