Good point, although I'd seriously laugh my HEAD OFF if one of the Ragnarok Wave found this odd drill shaped necklace...
And then did NOTHING with it. Ultimate fake-out McGuffin.
From a non-WAY-OUT-THERE technological idea:
Gradius' Vic Viper, or the ZOE Version (Variable Fighter heheheh)
Mechanaughts from Exteel
A/G/I/M-Gears from Flysis
And my #1 on the tech wishlist:
Bolos. Imagine having a BOLO with a female personality getting inducted into the ranks of the Valkyrie.
From a non-tech POV: I'd like to see the magical equivalent of the Jedi/Sith. References to LOTR, Harry Potter, D&D, Shadowrun, etc. Then have fun introducing a fully trained Jedi/Sith Wizard....
