I'd like to join a game based either on Space Battleship Yamato (Star Blazers) or Knights of Sidonia.

A shame I know neither of those anime series. How do you feel about The Expanse?

Haven't seen it.

Still Looking.

The Expanse is no where near Space Opera... it's more in what I'd call "Space Cyberpunk".

Or Space Cowboy (like Firefly).
I'd define the two series mentioned more as (to borrow a quote): In this one for the species.

I've been working on building a space opera game. Something really simple. But I'm still building it and it's not quite ready. But if you're interested you can take a look around here: link to another game

I could use some help finishing up the fine details as I finish writing up the campaign.

In reply to arkrim (msg # 9):

It looks quite good. I look forward to it opening as I already have a character concept. :)

In reply to Wynternight (msg # 11):

I'm pretty close. Just wrapping up a few things. Shoot me a DM or RTJ if you're interested.

Not familiar with either of your  referenced sources.  So, no idea if this would scratch your itch.
