I mean, looking at the map half of the border of Green Hill is taken up by ocean. I don't know about underwater bases, but securing the ocean near our start is probably smart. It would be bad if enemy ships sailed up on us before we were ready. Or Captain Metal and his pirate crew decided to take a bite out of us.I like Rexxon a lot more, but the Egg Golem is the smarter choice considering we can't use the Rexxon out of water and need defenses right now. but then I really wanted to make an underwater base that would be harder to reach and the Rexxon would be really useful for that...
fuck it I'm going with the Rexxon.
Not that we can build it right now, but it's good forward thinking.
