I have a copy of Esper Genesis, and yeah, it is based off 5th ed. It's ok, but it is a bit too, I don't know, focused(?) for my tastes...
yeah it has espers who get kewl powerz, but there are also 3 other power sources as well. it does shooty ships and FTL, but I want giant robots too. I want to custom build ships not pick one off a line. if Stars Without Number were 5th ed instead of OSR, it would be closer to what I want.
I'm looking forward to the revised edition of Ultarmodern 5th ed, which will include things like space ships, mecha, androids, magic, vehicles, and a bunch more. Still not exactly what I want tho.
Alternity was great, IMO, because it had so many bells and whistles that you could tweek. I want that. but 5th edition powered.
