Recently, SR.com user hebereke submitted some information regarding differences between Mechwarrior USA and Battletech. A submission with this information was offered, however, there was no speedrun video attached, however this was submitted recently to our leaderboard, I will attempt to confirm in the future. @ hebereke, if you see this post, perhaps you can elaborate further?

From what I understand, you cite the differences in the timing of the games yes, between US and PAL releases of the game for official speedrunning? If this is the case, then if we get enough runners for that category, it can certainly be added.
