Ofcourse you can try Kazaa. I used Kazaa to download a lot of games, like Civilization 3, Star Wars Galattic Battlegrounds, Clone Campaigns, Empire Earth, Heroes of might and magic, Virtua Fighter, Sim City 3000, Settlers 4, Mortal Kombat 4, Red Alert 2 and much more. But you should be careful, don't take too small files, they're probably virusses. And not ALL the games you download from KaZaA work.

You could also try to get a friend to temporarily give you the CD so you can burn or install it (it's how I got 1.23 for the first time), or ask someone to send it to you by internet (it's how I got 1.23 back, months later). Same with TSF. Easy.
