Hmm...reading teh description of Aberrant d20 (the one of the 3 I'm really all that familiar with) I'm not too sure I like the sound of things. however, I dearly love Aberrant and to help make sure that we have a chance at getting more Trinity Universe books published I'll buy at least the Aberrant d20 book.
So far, from various free systems like Paragon, Comic Book Super Heroes, and The Foundation; and pay systems like 4 Color to Fantasy and Silver Age Sentinels, so far my favorite system for super heroes is 4 Color to fantasy. I don't have the Revised version (and as I own d20 Modern and am kinda eh to it all I likely won't pick it up) but from the original version it's very interesting hwo you can blend it into regular D&D, how it all works as it's own game etc. Plus it looks quite easy to mimic super heroes I know well, much like Aberrant.
Also on Aberant, is it just me or was it WAY easier to make guys like Batman (lots of skills and I would give him a few low level mega attributes like Intelligence and such) Spiderman and Nightcrawler vs guys who are extremes like the Thing or Hulk. I can make a decent Thing with 50 points using the base rules, but he has a Taint of like 8 *grin*
Oh yeah, I will of course give Aberrant d20 a full chance, but until a more full fledged preview emerges I'm kind of down about the whole thing.
