Ixamyakxim: Morrowind might have been a popular best seller in that it sold a lot of copies for the day, but if I went into the house of any of my friends at the time and mentioned it the response would have been "Morrowhat? Never heard of that geek stuff. Now let's play some split screen - brah you better not pick the short guy!"
Morrowind was a pretty strange beast. While it was well-known among gamers (Bethesda accompanied the release with a very elaborate marketing campaign, complete with half a dozen of promotional videos), and sold decently (though not great) initially, it left many gamers confused and disappointed because it broke with genre conventions that they expected.
The main marketing slogan for Morrowind was "Live another Life", and that was also the leading motto during the game's design. Consequentially, the game was designed as a vast open world that gave the player lots of different options for pursuing the "career" they desired for their character, as well as giving them the freedom to completely ignore the main quest. This game, then, was sold to a generation of players who were used to "beat the game" being the main objective.
When the game explicitly tells you to leave the main quest aside for a while, go exploring, and gain some recognition in this world in whichever way you desire, many gamers were confused due to lack of direction (the backlash from this triggered the introduction of massive handholding later in Oblivion). Another common comment about the game's freedom of choice went like this: "Yeah, you can progress in a whole lot of different guilds, but it's all completely useless because it doesn't help you beat the main quest."
There were also lots of players who first gamed the leveling system (since they were used to this from other games), and then complained about the effects that that had on the game. Many players just didn't know what to do with the freedom that Morrowind gave them, and ended up being disappointed.
But over time, more and more people realized what the game had to offer, thousands of mods enhanced the experience, and the game became an incredible longseller.
JudasIscariot: I do believe a couple of the earlier Tex Murphy games got translated into German and French, even.
Mobygames shows that The Pandora Directive got translated into German and French and so did Overseer :)
edit: Under a Killing Moon looks like it got a German translation as well :)
Weird, seems that this is one of the series that simply bypassed my own personal bubble at that time. ;)
I'll have to ask my friends if they ever heard about the series. In any case, I recently played "Tesla Effect" and it made me quite curious about the previous games in the series. :)
