The game can be quite confusing at first. A good tutorial is available on the wiki here.
For an in-game tutorial, a game script has been implemented. Just download 'Beginner Tutorial' with the in-game download manager and load the 'Beginner Tutorial' scenario.

Tips and tricks
OpenTTD allows using a grayscale image as a heightmap for landscape generation. There's an excellent heightmap generator available at terrain.party, based on real Earth terrain. You may further use for fine-tuning the heightmap, especially useful are the Levels and Gaussian Blur tools.
A cheat menu can be shown in a local game by pressing Ctrl-Alt-C.
Detailed information about cheats are available here.
Music is not playing
The game will automatically try to use TiMidity++ with no additional arguments. If for some reason you need/want to use another synthesizer, OpenTTD provides the "extmidi" music driver, which allows you to configure a command to be ran to play music.
$PATH, you must specify the absolute path.
Edit your openttd.cfg to configure extmidi :
[misc] musicdriver = "extmidi:cmd=<command>"
openttd -m extmidi:cmd=<command>
However, extmidi does not allow additionnal arguments in the command. The solution is to use a wrapper script (for example,
#!/bin/bash #here, we want to use the FluidSynth synthesizer with the soundfont #provided in and PulseAudio trap "pkill fluidsynth" EXIT fluidsynth -a pulseaudio -i /usr/share/soundfonts/FluidR3_GM2-2.sf2 $*
Mark it as executable :
$ chmod 755 ~/.openttd/playmidi
Then you can specify the full path to the script as the command to be used with extmidi :
[misc] musicdriver = "extmidi:cmd=/home/<user>/openttd/playmidi"
