I recall Briliiance's interface as inscruitable.  But I don't think i ever got to try Brill 2.  I would like to though.  But it's no longer being sold AFAIK. So other methods are needed if I'm to try it.   Play became very anti-Amiga.  Look where that got them ;-).
Likewise i'd love to try PPaint 7.x.
Interesting note about DPaint 1 vs. the later versions. V1 used the Blitter for polygon fills.  It was instant.  Literally.  Needless to say we were bummed by v2 (and later)'s relative slowness.  They went to a software method for that, apparently to prepare for the port to the IBM clone.  If you never saw DPaint 1, go and grab it.  It's very quick.
>So while today's 18-24 year old "hardcore gamer" may not know the Amiga,
Idiots don't know what Sprites are either.
