These are the games I really enjoyed playing...
1) Roller Coaster Tycoon
2) Theme Park
4) Lemmings - alternative found: Pingus
Are there any alternative open source and run in Linux for the three above?
For Tetris, you could take a look at Tong, which is an extremely challenging cross between Tetris and Pong.
The idea of the game is - pieces fall and need to be rotated and slotted into spaces using the keyboard, as per Tetris, whilst you simultaneously use the mouse (or trackpad) to control paddles on the left, right, top and bottom of the screen to keep a ball bouncing around the screen, as per Pong.
To compound things, the game will randomly change the rules affecting the effects of the ball.
Depending on the rule that is active, if the ball hits a falling Tetris piece, it might bounce off the Tetris piece, or pass through it, or destroy it. Etc.
So you’re basically playing Tetris and Pong at the same time. It’s extremely frantic, infuriatingly challenging and actually - quite good fun!
