I was asking myself the same. Actually the game has not been updated since a while, when in Steam just some hours ago arrived the new version 1.47 with lot of new stuff, skills and more... Take a look here: http://youtu.be/BHLigqSGnLs

I'm afraid that, since the GoG version is single player (and it's complete), it has not been updated because multiplpayer is still in beta usage, but both the Steam version and the one sold in the main webpage http://www.unepicgame.com via Humble Store have multiplayer... :-(

I'm afraid we need to wait, OR go here http://www.unepicgame.com/en/comprar.html and waste again a litlle bit of money (9$) for trying multiplayer (getting also a DRM-free copy).

I think i will wait a little and see how it goes, but if it's not updated i will buy on steam on a deal if its possible,
thanks for the reply.

By the way, here are two guys from spain speaking english, LOL!!!

Hahahahahahahah!!!! I didn't notice!!! xD

Count me as the third!

As for updates, I recall reading that steam was a "testing" place, whereas both GOG's and Fran's site's version are stable and are only updated when the patches have been fully tested.
So, I think that the multiplayer will arrive at GOG, but not soon.
If you bought the game a long time ago here, you got the steam key anyway. I managed to get both keys, but it was about last summer.

Hello,

I just sent version 1.47 to gog team.
There will be new version very soon with:

1.- 30 new skills for weapons. Ubuntu sells them.
2.- Pannels can be resized.
3.- Special pannel for controller.
4.- New pictures for staves.
5.- New animation for magic essence.
6.- Inventory, spells and recipes can be sorted by pressing 'K'.

Great news, i'm glad to see the updates will arrive on gog too, the game is fantastic, good job Fran!!!

PD: and now four from spain!!!
