Personally, I'm turned off by the rips and Ragnarok characters of Wrath Steel, it doesn't seem to fit quite right and looks to have a simple BlizzardABS from the screens. Might not seem that way for everyone, so its just my opinion. So, the choice for me is between Locus and Planeswalker, which I honestly gave the same point scoring for both. Of the two though, I'd have to give my vote to Planeswalker for the level of enjoyablity.
EDIT: I've now played a little of the demo Astyanax: Wrath steel as well, and honestly I can't see the hype other than the nice rips. Perhaps people haven't downloaded the 118mb demo, but its really not that good. I mean no offense, Oracle. The dialogue/grammar is just terrible and often has serious typos, the story so far as I've played is cliche at best with a sixteen year old being pulled into a new world to save a princess (admittedly I have a ways to go still), and the battle system (which is the default BlizzardABS) seems to lag a lot. I don't mean to bash, but I really don't understand why this is getting so many more votes than Locus or Planeswalker.
