How can I compress much smaller than LZMA, that I want repack games?

All OK

You probably will get slightly better output with lolz instead of lzma, but it is much more time and cpu resources consuming. Keep that in mind.

If you want you can compress the soundtrack mp3's with srep+mpz

Edit:
Input: Soundtrack mp3's (unpacked zip file)
Method: mpz

Compressed 39 files, 469,898,266 => 369,460,114 bytes. Ratio 78.63%
Compression time: cpu 0.39 sec/real 64.55 sec = 1%. Speed 7.28 mB/s
All OK
