This was the first system I remember playing that had more than a single genre attached to it. For those that don't know what I mean, Palladium includes Robotech, Rifts, TMNT (Teenage Mutant Ninja Turtles), Heroes Unlimited, Palladium Fantasy and so much more. I believe Palladium may have coined the term "Megaverse", meaning that all the games in the system are interconnected. With Rifts, this allowed GM's and players alike to start playing in cross-venue games. People could play their mutants from TMNT into the world of Robotech or Rifts. This opened-up a large realm of possibilities that my fellow players and I took full advantage of.
My first encounters with the Palladium system was through TMNT. I remember making so many different mutants, from tigers to frogs and even a porcupine. There was even a memorial day weekend where to friends and I stayed in a mobile home outside of one of their houses to play a session of TMNT for the entire weekend. Those were the days.
Skills in the Palladium Megaverse were based off of a percentage system rather than ranks or dots. This made it very easy to understand where your characters strengths were. The method of advancement may be a bit flawed in some peoples opinions, but I think it works well.
Most of the games I've played in the Megaverse are:
Something I recently found out was that Palladium is aggressive in preventing wide distribution of fan-made conversions of their games to other systems (such as the D20 System), and also strongly discourages converting the intellectual property of others into their system; while they cannot prevent it, doing so is not allowed in venues owned by Palladium Books. Palladium also routinely threatens legal action against fans who distribute conversions in other venues by issuance of cease and desist orders. When asked why Palladium was so much stricter in regard to conversions than other game companies, Siembieda stated that the policy had been adopted due to advice from Palladium's lawyers, to shield Palladium from liability for conversions of other parties' intellectual property.
In the past when I've had to sell pieces of my collection to offset unemployment, I found that the books from Palladium never really held any type of second market value. I wonder if this is primarily due to an overabundance of books being printed by Palladium, or the seeming lack of interest the player community has in the system.
For around 3 years, 2 friends and I played in the Megaverse with multiple characters. Much of this was set in the Heroes Unlimited world. The above picture is what we came up with for a human version of the Invid's Royal Command Battloid from Robotech. If I remember correctly, this was modified to also run on modern or a nuclear fuel rather than what the Invid used.
