I am able to run L2 classic on slackware 14.2(multilib), but it segfaults on my GF's ubuntu as well, while same ubuntu machine can run Hi5 without any problems.
Pointing to the fact that L2 is made for windows is not an answer to this issue. Especially these days.
For example Hi5 is quite properly tested https://appdb.winehq.org/objectManager.php?sClass=version&iId=22855
While classic is not properly tested and has very poor ratings reported https://appdb.winehq.org/objectManager.php?sClass=version&iId=37392
Of course it might be just a matter of wine versions.
