The self-degrading application type of protection is a problem. Currently, if your copy fails the verification test it won’t install or won’t play. These new protection systems have less obvious failures. They will install and play but important game elements are modified if the verification check fails. Opponents become invulnerable randomly, weapons disappear, keys missing, random crashes, etc. Basicly, you think the copy is ok but it’s not. The end result is that you waste more time verifying that your warez are functional.
