I played the hunters origin with biogenisis, it was a lot of fun, but it breaks after a while and that's sad. I tried some lithoids next and things are the same. The game just falls apart midyear and crashes. It has something to do with colonization of new worlds. CREEEEE-ASSSSSSH.
Don't ask me about addons. Shhhhhh! Seriously, though, as a player who likes to go all out robot - Biogenesis has been pretty f-ing awesome. Way cool Stellaris. It took a moment to adjust to the new planet screen but I think I like that too.
