Actually, some of them were used as artwork for Solaris or Clan IIC machines.
ALF874- if you google "Solaris Skunk Werks", it's an English freeware Mech builder for Battletech. It also includes files of stats for many of the designs in later technical readouts, and will print record sheets for them as well. Might let you have fun with some new units!
Unfortunately there is no Japanese translate of recent battletech series (we don't have even aerotech or technical readout 3025 in Japanese language!), I have played battletech boardgame with classic inner sphere mechs only.
I wish I can play newer version of battletech and enjoy more battlemechs someday
That to bad, the current Battletech line has lots of new weapons and units, split between two technologies.
I lost internist in BT awhile back with all the Clan Invasion stuff, and how the rules are vary limited and incompatible with itself (using the wargaming rules with the role-playing games gets really messy). I hope you have the Silhouette core rules (SilCORE) in Japan, as its the best rule system for handling realistic games (wargaming & role-playing) with spacecrafts and giant robots. The system was made by Dream Pod 9, and was made for a VOTOMS-styled game called Heavy Gear.
Battlemechs in "Battletech Japanese Edition" were all redesigned by Mr.Kawamori(the artist of Macross) himself when Battletech was imported to Japan. ...Those "new version" 'mechs are still a bit similar to Macross though.
Awesome, man. I must to say... if I do use of the SAI today, it's because of you. I like your art so much, and it's great to see a every new piece of yours. When I be adult, I want to draw wonderfully like you.
