I've fiddled some with MFR this week and I have to agree, it's an amazing mod. The animal farms are easy to set up, work great and are fun to watch! I quite enjoy watching my cows frantically try to run the wrong way on a conveyor belt to escape the mob grinder... sometimes it takes a few minutes, but they always succumb eventually. *evil laughter*
MFR makes biofuel production so easy, I almost feel guilty about skipping the fermenter/still/mulch/fertilizer. Almost.
Put a pair of villagers next to the breeder machines with those (expensive) syringes and tell me what your face is like when you see what happens. Image macros are preferred. It is best to let your hope build for awhile first.
