I see your point, if you don't want built-in chat, or to play IPX games over TCP/IP, it might be over kill. But the stability and speed of the server refresh is worth $16 for lifetime use to me (it seems twice as fast as the free ASE version...)
Oh, no adware or spyware either
lol about Mech 2, I used Kali for that game too. Ah the good ole days. The very first Command & Conquer didn't play over TCP/IP, but me and a few friends on the west coast used Kali to play it all night for months on end.
