I say we should see some Ssi-Ruuvi models... they're so underexposed... such wonderful, soul enslaving creatures... It'd definitely be something new. I have to use Dessan for now... not quite the same thing.
As for a mod... I saw someone wanting a remake of JK 1... how about a remake of Dark Forces 1? That was a sweet game... sure, no force powers, but... DARKTROOPERS! Yes, that'd be another nice model, as well... a darktrooper. I see someone already mentioned that one.
