Okay - you want scifi, I've got you covered!
MOJI doesn't update frequently, but looks like it's shaping up to be a fun adventure. Desert landscapes on distant planets, alien unicorn-cows, giant robots.
KISMET - super-clever scientist woman meets non-human man who doesn't quite know WHAT he is. Together, they fight giant cyclopean monsters with lazer-guns. Is KISMET the prettiest comic on Tapastic? I have no idea, but it sure stands a fighting chance!
SPEJS - dorky, silly, fun space opera, with grumpy bounty hunter ladies and cute cinnamon roll space-trucker men. Why are all my recommendations so far in all caps? Who knows!
And finally, a bit off the brief, but still:
Drugs & Wires - more a dystopian-cyberpunk-90s thing than straight up scifi, but super-well told story set in a world where cyberware and computer viruses have become an alternative (and complement) to drugs and alcohol. Our hero is a wreck of a human being with a malfunctioning brainjack.
