I never got into Battletech back in the day. I had played it at Gencon once - with the heat sinks but it never really grabbed me. I did get into the Mechwarrior Dark Age when it came out from Wizkids and even was a Warlord (judge) for a few of the sets.
I just got the classic rules from ebay yesterday. I'm going to check them over to see if they are viable for Wincon. I'm still very interested in the system from an upsizing view. From the book, I found out that the nice people at Armorcast used to make 28mm scale Battletech mechs. They look keen and inspring.
