So I noticed earlier on the Q&A that pricing was expected to be around 20-30 euros and on top of that LIF MMO will probably be free of charge for those who bought LIF YO..
I have to say I think you're selling yourself short. 20 euros is about as low as you can get. I understand a full 60 euros may be a bit much for an indy game but I suggest you charge at least 40eu considering the huge amount of content of this game.
I would also advice you to not give the MMO free to those who purchased the YO-version, a discount might be appropriate though.
I write this primarily beacuse I know you are working on a limited budget right now and I really think you are underestimating the value and appeal of your product.
