Saw this a long time ago, after my experience with this trash I will personally never touch another game published by Chinese companies again.
Annoys me because it could have been really successful had they chose to monetise the game correctly (for a start having gold drop in-game, and allowing players to buy it off eachother. Not buying spawned in gold off the devs). I won't go into a big list of what was wrong with their monetisation but yeah, pure ****ing greed basically.
Basic bugs such as the trade system not working on the English client (I'm serious) were never fixed all the way until it shut down (I used to login and check up on the game periodically) and apparently (according to Sprite who seemed to have insider info) the game was being run by more than 1 person. I mean ****, their website didn't even have proper SEO. Getting on the first page for the search term "Legend of Mir" would have been sufficient marketing alone. Just basic **** I could have quite easily done myself as the sole manager of the game, a whole Chinese team were completely incapable of.
To be fair, look at all the websites that come out of China, even the really popular ones. All look like ****, of course they can't run an international MMORPG.
EDIT: Would be awesome if these files get leaked / emulated and we can have a proper Mir3d server. Their official server standards are worse than our privates haha.
