I feel it has improvment for some performance aspect, but . . .

• Still occured random crash when apply setting in-game.
  
• And also randomly wild crashes appear without any message while in-game.

Yep, there is a multiplayer mode here and also on last non-steam version indeed, with some difference like:

• Some replacement improvment that change gamespy with steam game netwok.
  
• If you login to steam network, you can do steam chat at lobby/launcher and also in-game multiplayer session.

It's like dejavu playing this version.
I only recommend to buy this game for you guys that want add this simulation to your account for digital asset or something like that.

Note:
Oh yeah, there is so many of positive reviews come from people with less than 1 hour game play, dude are you allright?

I don't know how to play, make my money negative, get an achievement.

100/10

The simplest complex puzzle game that ever made.
