Welp, I've officially spent some money on digital. That Comixology Archie sale for Valentine's day? They may have excluded the horror stuff and the superhero stuff, but they apparently care so little about the Sonic and Mega Man stuff that they forgot to exclude it. So I finally got my Sonic sale, and went ahead and filled in all the gaps from the cancelled trade lines onwards, and then said screw it and got the rest needed to catch them up. So now I think I'll actually be buying the mainline Sonic series and Universe monthly on Comixology from now on. Decided that their trade shenanigans aren't worth putting up with, so now I'll just grab them when/if they actually come out instead of driving myself nuts over endless delays. Which I suppose is probably giving them more money for their terrible trade release scheduling, but whatever. Mega Man and Sonic Boom I'll wait out on the hopes that those won't take an eternity to finish since they're done (though hopefully Mega Man will come back from its "hiatus" eventually), and hopefully won't take an eternity to catch up (versus Sonic Universe being now like 50 issues behind the singles in trades thanks to all the delays). So yeah, interesting reading ahead of me, I guess, and a lot of crap.
Also, I'm kind of sad that apparently they don't have all of the terrible old Knuckles series on Comixology. I'd throw the $30 or whatever to get all those on sale, since from what I know those may well be the worst comics ever made (well, without including stuff that goes into actively offending with their existence rather than poor quality, I guess).
But yeah, heads up that this works, as the more recent Sonic stuff and especially the Mega Man series are great, so if you want 50% off those digitally you can get them today.
