Let Confusion reign!

[Conquistador]

Other than http://rpg.drivethrustuff.com/browse.php?manufacturers_id=5603 with "snippet comment" reviews does anyone know about the "assorted" Empires Colossus set of rules - are the D6/D10/D20 versions the same just with different dice results * or are there system "changes" (possible odds incompatibilities?) or do the core rules change between versions (like "dice-less") too to adjust probable outcomes?

Found this on a rare anonymous viewing of TMP and was totally lost as to the game's style of play...

Gracias,

Glenn

* by this I mean you hit on a 4+ on D6 and an 11+ on D20 type cosmetic changes that have the same probability.
