Crusader Kings 2 has a demo at Fileplanet of all places.
IT IS WORTH PLAYING. This is the best polished and most stable Paradox Interactive released EVER. I played for 12 hours yesterday with NO CRASHES AT ALL.
The demo is FULLY FEATURED. Everything in the game is in the demo. BUT there are two catches.
1) You can only play as 4 powers.
2) You can only play for 20 years.
NEVER FEAR! Enterprising fans have figured out workarounds to the first two points, both of which have been openly discussed on Paradox Interactive's Boards without a ban (and so, presumably, are semi-legit)
Workaround to #1:
Select any of the four available characters, and press start game. There's a brief delay before the game starts to load. During that delay, if you click on a county on the map, you will instead play as THAT power!
Workaround to #2:
To get more than 20 years of play, make sure Crusader Kings 2 is not installed to your Program Files directory. Go download GAWK, and make sure that it isn't installed to Program Files either. Then go download the script at the following link http://forum.paradoxplaza.com/forum/showthread.php?583150-Cheats-%28In-Demo%29&s=d13a0cc82ba5ccd72d230db788c295b0&p=13401700&viewfull=1#post13401700
Edit the .Bat file in the script to read as follows
IF not exist ck2demo.exe (
echo not in ck2 directory
echo awk needed, make sure it's installed!
echo creating backup directories
echo creating backup
FOR /F "delims=:" %%i IN (textfiles.txt) DO copy "%%i" ".\backup\\%%i" >NUL
copy ".\common\defines.lua" ".\backup\common\defines.lua" >NUL
echo modifying files
FOR /F "delims=:" %%i IN (textfiles.txt) DO C:\"Games"\GnuWin32\bin\awk.exe -f awkskript.txt <".\backup\%%i" >"%%i"
FOR /F "delims=:" %%i IN (textfiles2.txt) DO C:\"Games"\GnuWin32\bin\awk.exe -f awkskript2.txt <".\backup\%%i" >"%%i"
FOR /F "delims=:" %%i IN (textfiles2.txt) DO C:\"Games"\GnuWin32\bin\awk.exe -f awkskript3.txt <".\backup\common\defines.lua" >".\common\defines.lua"
Where "Games" is replaced with the path of your GAWK directory.
If you do all this shit, promise me you buy the game. It is fucking worth it. PEACE
