[The Son of Horus]

I'm not sure whether this goes in "off topic" or in here, so if I got this wrong, I'm sure a mod can move it.

Battletech was what got me into miniatures games, and it remains close to my heart. With the recent releases from Catalyst Games, I've been messing with it quite a bit lately (and painting 'mechs has significantly detracted from progress on the Lions Rampant...) and it occured to me that you could very easily take Epic scale Titan models and use the Battletech rules with them. There isn't really a good system out there for having titan-on-titan combat, and it seems like Battletech might actually be a good answer to that. Just thought I'd throw that out there. :lol:

This seems the right place for this as it is still 40K related. I haven't played either system but you raise a good point about the whole mixing systems idea and their legitimacy.
