1. SP 7 worlds, 7 chars, & diff progressions. 3 i think i took to Yagluth. 2 i haven't beat any bosses (1 to see how far i can progress with out doing so... got to iron and lost interest. the other is creative.) 2 MP worlds. 1 got to Bonemass b4 being shut down, the other is at Eikthyr.
2. I think i just past 740 total. First had probably the most hrs... maybe 300ish. probably 100 in creative. maybe 200 ish in MP. One world has maybe 25-30 hrs in it, that was a speed run to beat yagluth.
3/4. Axe/bow tends to be highest fighting skills for me. Current playthru Axe is at 59, bow at 48 (one death). I think that's about average for all my char's though, even the one's i've died a lot on. Those tended to be early chars and had more time overall on them. Generally though I really only ever think about the Running and Jumping skills in the early game. Those two skills are the only ones I consciously try to improve to a point where they are no longer such a pain.
The exception to all this the char on my creative world. I maxed the stats out on that one. ♥♥♥♥♥♥♥♥♥ is the bow op at max skill! It's a machine gun.
5. Current play thru 'running': 69 'tree-cutting': 59 'mining':72
6. What do I spend most of my time doing? What we all do: Fighting greydwarves while mining/treecutting.
7. Cheats only on my creative char, other wise see 3/4 above.

I was looking at others screen shots the other day, and got interested in how others set up their hotbar. I go 1 weapon, 2 shield, 3 bow, 4&5 tools, 6-8 food.
