I can't recall about MekTek but in Living Legend's case, it was highly suspicious. It sure seemed like PGI's pressure, even if it wasn't.
Though wasn't Infinite Games handling stuff then? I recall something about them being the real problem.
Straight from the horse's mouth:
Greeting Living Legends!
In light of recent confusion and rumors, the co-owner of Wandering Samurai Studios and I are here to clear some things up.
First and foremost there has not, nor has there ever been, any legal action or threat of legal action leveraged against the MechWarrior: Living Legends development team. This was an assumption of a small amount of volunteers based on incomplete information.
To clarify, the decision to discontinue development of MechWarrior: Living Legends was made by the founders and owners of the project. On behalf of all the people involved in MechWarrior: Living Legends we must sincerely apologize to all parties affected by this miscommunication.
In closing, development on this project has officially come to an end. We thank you for your support and express our hope for the continued success of the MechWarrior franchise.
