I would like to recommend to anyone who loves the Adventure Game genre that you purchase and play the new Riven, just released back in June.

And for anyone who played and loved the 1997 version, you will find the remake, fully rebuilt in Unreal Engine, to be as good or better across almost every dimension. While still being very faithful to the original, some logical changes were made, and with some solid additions to the worlds and to gameplay which give it new life.

Cyan is and still is a small, indie game developer, and relies on word of mouth to be seen in a very crowded field of titles -- especially on Steam.

I bought it here hoping Cyan would get a better cut of the sale price than at Steam, but I'm a little surprised that there's not more discussion around it here.

So give it a go! Players familiar with the original are cautioned to try to take your time, savor getting reacquainted with an old friend, and play through the game as if you had never played it before, or you will probably miss stuff you don't want to miss.

There is some discussion in the sticky post. Steam version has achievements and GOG version still doesn't, although they said they're working on it, so let's hope they'll add them at some point. GOG uses Steam SDK API for unlocking achievements - it basically imports Steam achievements automatically for the English version. Maybe they want to add localised achievements too or not at all if their only option are English achievements.
