The A/I leaves much to be desired in JTCS (Campaign Series). But playing H2H or in PBEM, it is an awesome game!!
But the good news is, with scripting, as the Dev Team is doing with Campaign Series Vietnam the A/I is so so much better!
This will be extended to the new generation of games going forward.
$9.90 for all the content in the Campaign Series is a great price and a bargain!
