I had many a lovely campaigns in the original STW and in SWs; SP can be very enjoyable, few units or many its how you use them that counts and the overall atmosphere that accounts for immersiveness, but admitedly few fans will consider things with few units as things turned out now.

MI was awful "a bunch of bad superman invade join the fun with them or the struggle to repel them!" The battles were all the same with the Mongols either with or against them.
