I agree with this, though for the record golems aren't even in the same league as turtles (IMO only Steve's Factory Manager is). Regardless, the mechanics are fun as hell, that much is true.
That's the main reason I hate the research so much, really. It just gets in the fun I could be having with the mod.
I also agree Turtles are hella powerful. I had a blast writing a few Lua programs myself, my most polished of which is a (up to) 20x20x2
Peat Farm. I missed the MC 1.4.7 Forestry Peat Farms and found the Multifarm version to be lacking, so I made my own.
The golems, however, are a nice change of pace. No Lua required and they're pretty fun to watch. I've watched more than my fair share of Turtles doing their job, and even more time *not* doing their job, i.e. going off into the weeds, due a bug in my Lua code ;-)
