Big time seconded. We need more aliens. Well, we need more well-fleshed out aliens. Sure there's the Ultimate ALien Anthology, but some of those aliens are pretty weak. Plus I'd like to see aliens that are less like anthropomorphic beasties and more alien.
A modern-day horror (ala Buffy, but with less goofy) setting would rock as well.
I have to second a compendium of cybernetics as well.
I also have to voice my support for Prometheus Rising becoming a more fleshed out setting.
Beyond that, I would like to see:
Update to Blood and Vigilance. Even though M&M2 is my primary supers game, I still use B&V in my Rift-ish Modern games. However, like others have said there are some balance issues that need to be ironed out.
Small enclave and location examples for Darwin's World would be great as well. Nice fleshed out settlements, or raider group hideouts would be helpful.
All in all, though, RGPObjects has been doing a great job to meet my D20 Modern needs. Keep up the great work!
