I try to do all-female runs of every Super Robot Wars. Not on my first playthrough, mind you. I'm not that crazy.
So far, I've done MX, Alpha 3, OG Gaiden, and K. I'm in Alpha 2 and 2nd OGs right now. I haven't done it on 2nd Z Saisei, but I could if I wanted to. It's not really feasible in W, because that's such a male-tilted game. I wouldn't want to do it in L, because I don't like it all that much. I haven't gotten to it in J because I'm on my first Touya run in English. I'm pretty far in, but I'm just lazy. I don't have enough money in A Portable, but that game's not that great, anyway. Don't like regular A enough. Doing Raul in R right now, or I should, I dunno. I get really nihilistic sometimes. Not bothering with D because I can't get into it. I'm not even sure if you have enough characters. I COULD do Z. Kind of in a Rand playthrough now, though. At least Special was easy to unlock in that.
Not bothering with OG1s (probably not enough characters or high enough attack power), but I could in OG2s. Note that "OG2s" and "OGs2" are different things (the former being the PS2 version of OG2, the latter being "2nd OGs" on PS3). A lot of the old games aren't high-powered enough (no PP) and are skewed towards main characters and the like. The one thing I can say is that the older games let female characters have Soul. Nowadays, you never see it outside of birthday selections, or when Asuka from Eva or Ryoko from the Nadesico movie is involved. Well, it's in the Original Generations tri-duology or whatever it's called, because of Katina (no surprise there; even with five spirits she has it @ 55 SP).
I know it's not very accomplishment-y, but I don't do anything impressive or get lucky whatevers. I can play Idea Factory games without my brain melting out of my ears in sheer boredom/badness, but I think that means I'm insane.
