So here are the things that should probably happen to Gigacrawler before anyone goes around calling it a game. If you're feeling creative, here's what we need...
-Alterations. We have plenty of mutations/cyborg stuff/etc. though some industrious soul(s) should take a look at them and think: can I pretty much build most of the "playable" aliens and mutants I can think of using these rules? Like: Wookie, blob guy, animal-people (if you've got one of those animal encyclopedias at home that'd be good, any given Green Lantern (except Mogo or Dkrtzy RRR--though if you can rig a sentient mathematical progression as a playable PC race, you rock), any miniature you own (etc.). Claws, teeth and extra limbs will cover 9o% of it but is there, say a chameleon-like ability in there?
-At least half again as many martial arts. Go crazy.
-Devices. We got lots of devices. While covering every possible sci-fi device is not necessary (we need something left over for treasure) someone could look through the list and make sure that all the basic modern adventuring gear is represented: a plausible range of low-level weapons, life-support devices, ten-foot pole, flashlight, etc. Look through a modern RPG and your camping/hiking/mountain climbing shopping list and make sure it's mostly covered.
-More spells. You might wanna take a look at the extant spells and make sure there's a decent spread of low, medium, and high-level stuff. And you can never have enough madness and weirdness. There's like 45 so far.
-Setting features. Looking good here--especially on the tech end. Maybe a few more esoteric/magical ideas. Also, we could arguably use more monsters, so if there's any beastie you want in there before the game goes "official", there you go.
Coffee selfie. Taking an early break.
