BattleTech Movement Rate – To – Max Profitable BattleMech Tonnage Guide for Munchkins
A bit, after seeing Brian Sugrim in michigan 8/11-8/15 in Kalamazoo, Michigan, I got back into BattleTech a little bit, mostly on influence on his 5-year old son being big into transformers. The tangent is that BattleMechs are largely humanoid, and in the case of Land-Air ‘Mechs, they are transformers as well, but piloted war-machines rather than self-sentient robots. Imperial Walkers in Star Wars (AT-AT and AT-ST) could be technically BattleMechs also, but much heavier. I havn’t touched my BattleTech stuff much since I was 19 or 20 (1994-1996). I only have the boardgame, Compendium, and Mechwarrior RPG, but now, I have nearly every BattleTech book now (some hoarded back in 2004 but a lot of new ones recently), in PDF, thanks to eMule!
I made a max-tonnage for a desired movement rate munchkinning guide for you BattleMech designing munchkins like me. Pick the engine type (Normal, Light , eXtraLight, eXtra-eXtraLight), and a movement rate. Then get the max total ‘Mech tonnage that you can have with that movement rate before you actually start losing tonnage available to armor, weapons, electronic warfare, and other eqipment rather than gaining due to the tonnage increase from the engine (fusion reactor) + gyro + internal structure exceeds the tonnage increase of the overal unit. You can have a lower weight BattleMech for the given movenet rating, but not higher, else you will have LESS space for weapons and such rather than MORE.
