Personal Favorite Achievement of 2012: I can't really think of anything as awesome as perfecting MoF extra stage that I've done, and that was back last December I think...(checks date)...February 9th, 2012. Yep, still that, even after all this time. Though my GFW lunatic 1cc, done on 9/9/12, comes pretty close (if you haven't seen it, my first clear ended with over 800 motivation).
Personal Biggest Screw-up of 2012: Hands down getting completely walled off on Kagome Kagome, dying, continuing the run and perfecting the rest of Flandre, resulting in a very very painful 1DNB EoSD extra. Also up there is dying 3 times to Subterranean Rose after perfecting Koishi outside of Rorschach, and blowing an MoF lunatic no bombs attempt on Sanae by getting hit 4 times.
Favorite Achievements by Others of 2012: I think Funen got his MoF lunatic no bombs this year? I don't expect mine to be as awesome as that, but I'm hoping I get a certain stage perfect in mine that he missed

Seppo Hovi's IN ultra Stage 4 lunatic spellcard captures let me know they were all possible, otherwise I would have taken 1 look and gone "no". SirChaotick's MoF lunatic 1cc, along with everyone else who got a first lunatic clear this year, because I remember what it was like to manage that for the first time.
Oh right, this section can't be done without an extra shoutout to EVERYONE who participated in
Double Spoiler Done Quick and especially also ARF for singlehandedly doing/saving
Shoot the Bullet Done Quick. :toot: :dragonforce:
Goals for 2013: MoF lunatic no bombs, UFO lunatic, actually getting that perfect run of Youmu, beyond that we'll see what I end up doing. Maybe PCB lunatic no focus?
[OPTIONAL] CHALLENGES TO OTHER PLAYERS: Hey Seiga, go get that perfect of Nitori, I think I remember you saying you don't have that one yet and I perfected Stage 3 in my last no bombs try so :getdown:
Zengeku: play a credit of Ten Desires and enjoy it. That should be a nice challenge :getdown:
Nindella: go an entire stream session of your standard 5 hour length without mentioning Orin. Or is that impossible? :getdown:
Riz: Get those last 3 LNBNUFO runs before next year. You can definitely do it and they're really awesome to see. :getdown:
Everyone on MoTK: let's get that replay uploader to 50,000 replays by this time next year!
edit:
Hey Sapz what are your picks for each of those categories? :V
